When heat is supplied to material, its dimensions(length, area, volume) can be changed due to change in its temperature.The phenomenon of change in dimensions of an object due to heat supplied is known as thermal expansion. Types Of Thermal Expansion There are three types of thermal expansion.(I) Linear Expansion(II) Area Expansion(III) Volume Expansion (I) Linear […]
Absolute Zero Temperature Theoretically, there is no limit for maximum temperature but there is a sharp point for minimum temperature that no body can have the temperature lower than this minimum value of temperature which is known as absolute zero temperature. Absolute Zero Temperature From p-T Graph The variation of pressure(P) with temperature(T) can be
There are three characteristics of gas which describe its behaviour. These are pressure(P), volume(V) and temperature(T). The relation among pressure, volume and temperature of a gas is given by these two laws. (1) Boyle’s Law It is given by English chemist Robert Boyle (1627-1691). According to this law at constant temperature, pressure is inversely proportional
Heat is the form of energy which flows from hotter body to colder body by virtue of temperature difference. The process of transfer of heat is a non-mechanical process i.e there is no mechanical work involve in the process of heat transfer. The amount of heat is measured in joule (SI unit) and other widely
Temperature is the measure of degree of hotness or coldness of a body. The measurement of temperature of a body is a relative measure. We can consider three body with temperature T₁, T₂ and T₃, where T₁>T₂>T₃ then the body T₁ is called hotter one with respect to another one which is known as colder
