    convection process rather than mechanical transmitting source‚ which captures the heat energy of sun and delivers it during winter and pumps out the heat in summer‚ using heat distribution methods. Some of the heat distribution methods are Convection‚ Conduction‚ and Radiation. However components of passive solar heating are‚ the aperture area of the house‚ absorber area of the house‚ thermal mass of the house‚ heat distribution‚ and solar control. When these components work together it contributes

    An intensive property is a bulk property‚ meaning that it is a physical property of a system that does not depend on the system size or the amount of material in the system. Examples of intensive properties are the temperature and the hardness of an object. No matter how small a diamond is cut‚ it maintains its intrinsic hardness. By contrast‚ an extensive property is one that is additive for independent‚ noninteracting subsystems.[1] The property is proportional to the amount of material in the

    The importance of water in Biological Systems Much of the Earths surface is comprised of water‚ as well as much of biological systems; for instance‚ the human body consists of approximately 70% of water‚ and in other biological organisms this figure could even be 95%. This largely relies on the bonding of water‚ whereby two hydrogen atoms bond to one oxygen atom; hydrogen bonding is the strongest intermolecular force due to its high polarity. Hence‚ what is the biological importance of water?

    water plays a part in this. One method of reducing internal body heat is sweating; sweat is mostly made up of water. The structure of the water molecule means that it has very high melting and boiling points for a molecule of its nature because of the strong attraction between them. This means that a large amount of energy is needed before the molecules begin to move about and therefore change state. It is because of this high latent heat of vaporisation that water is an effective coolant; energy from
