Definitions:

Heat- It is the form of energy transferred between two (or more) systems or a system and its surroundings by virtue of temperature difference. The SI unit of heat energy transferred is expressed in joule (J).

Charles Law- When the pressure is held constant, the volume of a quantity of the gas is related to the temperature as V/T = constant. This relationship is known as Charles’  law.

Thermal Expansion- The increase in the dimensions of a body due to the increase in its temperature is called thermal expansion.

Linear Expansion- The expansion in length is called linear expansion.

Area Expansion- The expansion in area is called area expansion.

Volume Expansion- The expansion in volume is called volume expansion.

Heat Capacity- The change in temperature of a substance, when a given quantity of heat is absorbed or rejected by it, is characterized by a quantity called the heat capacity of that substance. We define heat capacity as S.

Specific Heat Capacity- Every substance has a unique value for the amount of heat absorbed or given off to change the temperature of its unit mass it by one unit. This quantity is referred to as the specific heat capacity of the substance.

Molar Specific Heat Capacity- If the amount of substance is specified in terms of moles m, instead of mass m in kg, we can define heat capacity per mole of the substance by heat capacity divided by mole, where C is called molar specific heat capacity.

Molar specific heat capacity at constant pressure- If the gas is held under constant pressure during the heat transfer, then it is called the molar specific heat capacity at constant pressure and is denoted by Cp.

Molar specific heat capacity at constant volume- If the volume of the gas is maintained during the heat transfer, then the corresponding molar specific heat capacity is called molar specific heat capacity at constant volume and is denoted by Cv.

Calorimeter- A device in which heat measurement can be done is called a calorimeter.

Melting- The change of state from solid to liquid is called melting.

Freezing- fusion and from liquid to solid is called freezing.

Melting Point- The temperature at which the solid and the liquid states of the substance are in thermal equilibrium with each other is called its melting point.

Normal Melting Point- The melting point of a substance at standard atmospheric pressure is called its normal melting point.

Vaporisation- The change of state from liquid to vapor (or gas) is called vaporization.

Boiling Point- The temperature at which the liquid and the vapor states of the substance coexist is called its boiling point.

Normal boiling point- The boiling point of a substance at standard atmospheric pressure is called its normal boiling point.

Sublimation- The change from solid state to a vapor state without passing through the liquid state is called sublimation, and the substance is said to sublime.

Latent heat of  fusion- The latent heat for a solid-liquid state change is called the latent heat of              fusion (Lf)

Latent heat of vaporisation- The latent heat for a liquid-gas state change is called the latent heat of vaporisation (Lv).

Conduction- Conduction is the mechanism of transfer of heat between two adjacent parts of a body because of their temperature difference.

Convection- Convection is a mode of heat transfer by actual motion of matter. It is possible only in fluids.
