Water Properties and Facts You Should Know

Water Properties and Facts You Should Know Water is the most abundant molecule on the Earths surface and one of the most important molecules to study in chemistry. The facts of water chemistry reveal why this is such an incredible molecule. What Is Water? Water is a chemical compound. Each molecule of water, H2O or HOH, consists of two atoms of hydrogen bonded to one atom of oxygen. Properties of Water There are several important properties of water that distinguish it from other molecules and make it the key compound for life: Cohesion is a key property of water. Because of the polarity of the molecules, water molecules are attracted to each other. Hydrogen bonds form between neighboring molecules. Because of its cohesiveness, water remains a liquid at normal temperatures rather than vaporizing into a gas. Cohesiveness also leads to high surface tension. An example of the surface tension is seen by beading of water on surfaces and by the ability of insects to walk on liquid water without sinking.Adhesion is another property of water. Adhesiveness is a measure of waters ability to attract other types of molecules. Water is adhesive to molecules capable of forming hydrogen bonds with it.  Adhesion and cohesion lead to capillary action, which is seen when the water rises up a narrow glass tube or within the stems of plants.The high specific heat and high heat of vaporization mean a lot of energy is needed to break hydrogen bonds between water molecules. Because of this, water resists extreme temperature cha nges. This is important for weather and also for species survival. The high heat of vaporization means evaporating water has a significant cooling effect. Many animals use perspiration to keep cool, taking advantage of this effect. Water is a polar molecule. Each molecule is bent, with the negatively charged oxygen on one side and the pair of positive-charged hydrogen molecules on the other side of the molecule.Water is the only common compound that exists in solid, liquid, and gas phase under ordinary, natural conditions.Water is amphoteric, which means it can act as both an acid and a base. Self-ionization of water produces H and OH- ions.Ice is less dense than liquid water. For most materials, the solid phase is denser than the liquid phase. Hydrogen bonds between water molecules are responsible for the lower density of ice. An important consequence is that lakes and rivers freeze from the top down, with ice floating on water.Pure liquid water at room temperature is odorless, tasteless, and nearly colorless. Water has a faint blue color, which becomes more apparent in large volumes of water.Water has the second highest specific enthalpy of fusion of all substances (after ammonia). The specific enthalpy of fu sion of water is 333.55 kJ ·kg−1 at 0  °C. Water has the second highest specific heat capacity of all known substances. Ammonia has the highest specific heat. Water also has a high heat of vaporization (40.65 kJ ·mol−1). The high specific heat and heat of vaporization result from the high degree of hydrogen bonding between water molecules. One consequence of this is that water is not subject to rapid temperature fluctuations. On Earth, this helps to prevent dramatic climate changes.Water may be called the universal solvent because it is able to dissolve many different substances. Interesting Water Facts Other names for water are dihydrogen monoxide, oxidane, hydroxylic acid, and hydrogen hydroxide.The molecular formula of water is H2OMolar mass: 18.01528(33) g/molDensity: 1000 kg/m3, liquid (4  °C) or 917 kg/m3, solidMelting point: 0  °C, 32  °F (273.15 K)Boiling point: 100  °C, 212  °F (373.15 K)Acidity (pKa): 15.74Basicity (pKb): 15.74Refractive index: (nD) 1.3330Viscosity: 0.001 Pa s at 20  °CCrystal structure: hexagonalMolecular shape: bent

The Jainist And Carvaka Approach Ethics Are They Compatible Essay

The Jainist And Carvaka Approach Ethics Are They Compatible - Essay Example An individual who consistently becomes upset, discontent with the world, egotistic, and selfish towards the people around them grows into an individual with no peace of mind and the desire to accept the worldly situations as they are. The Jainist approach to ethics loathes fear of the legal system or individuals of the higher authority as this demonstrates the karmic bondage of such a person according to the karma philosophy. Jainists discourage actions that are associated with hypocritical practices aimed at enhancing exploitation of the weak and the vulnerable for material gains only (Kalghatgi 236). All individuals in the Jainist approach should aim at the achievement of happiness and peace of mind due to the fact such individuals possess the power to understand that commitment and equanimity begets happiness and personal satisfaction. The desire to revenge due to anger and resentment fuels violence and provides no room for peaceful solutions to available crises. For example, issu ing threatening remarks towards a terrorist as a way of controlling their actions has no impact at all, as it increases the resolve of the terrorist to continue with their activities. When the United States of America decided to enter the Gulf region to retaliate the attacks by terrorists, the solution to terrorism was sent to a mirage position as the criminals’ resolve was doubled (Koller 157). The Carvaka philosophy also traces its roots to the Indian philosophical development, and it assumes forms that go to materialism, philosophical skepticism, and indifference to religion. The development of the Carvaka philosophy arose from the orthodox Hindu and the Nastika philosophical developments in the early 17th century in India. The development of Indian philosophical work has... This essay stresses that the Carvakans skeptical analysis strengthens the resolve that there is no hell that possesses an excessive pain as that experienced by the current form of life in the world. It, however, agrees on the presence of a supreme who is the monarch of the earthly materials and whose actions and influence are both visible and can be felt in different ways. In their preposition, it is evident that the Carvakans committed a fallacy when they insisted that the fact that an event or object which is not known to exist cannot exist in any form. This paper makes a conclusion that the religious conceptions as explained in Jainist are rejected by the Carvakans philosophies. The Pianist advances the belief in the presence of animate and inanimate entities whose souls do not interact at any level. It, thus, believes in the presence of another form of life, a sort of reincarnation after the physical death on earth. This is against the ideals of Carvakans, which rejects the ability of an individual to escape the power of death and emerge in another form. This position placed the Carvakans philosopher at a collision course with the Veda proponents who also subscribed to a theoretical reference to reincarnation (Koller 159). To the Carvakans, any individual attributes that were used to represent an individual resided solely in the body and could not be replicated in another form after death in a process similar to reincarnation.

A Critical Evaluation of Your Learning and Development Whilst on Work Placement - Assignment Example The main aim of the module is to enable learning from the entire work experience that includes a focus on knowledge from the workplace and generic skills. These comprise of: induction programs, understanding organizational structures, learning through induction, personal development and critical analysis (Peter, 2009). Much of my educational learning is about gaining of subject knowledge and development the critical and analytical skills related to my subject. This is a very important fact; however, what is also vital is that I can apply this academic knowledge and, more exclusively, the kinds of thinking skills I gained through education to a more practical context of work (Sammon, 2008). With ever changing knowledge, I also need to be very practical and adaptable so as to cope with these demands. Therefore, this module is generally aimed to help me: develop my personal and key skills, increase my employability skills, improve on my strengths and weakness, become a reflective practi tioner, be able to utilize effectively transfer of skills, become an autonomous learner and finally to be able to learn by experience. MODULE STRUCTURE 1) Learning through self-awareness 1.1) knowing and understanding my learning style There are numerous means that a person can learn. The more can be able to understand our preferences to learn, including developing and practicing various ways of learning and hence the more we become effective learners in different contexts (Peter, 2009). According to Kolb (1984), as we grow up, we build up tendencies and preferences to learn new things in some specific way, without essentially noticing that it is so. My learning style is basically linked to Kolb’s four stages of learning as shown below: 1having a strong experience doing 4. Testing planning 3. Conceptulizing 2.reflection/ observation review To be a more effective learner I would wish to improve on these selected areas. 1.2 Personal and key skills Many generic skills are for ef fectiveness at work or daily lives, for instance problem solving, good communication, time management, setting goals.
