## Important Topics for HC Verma Concepts of Physics Part-2 Solutions Chapter 25: Calorimetry

Units of Heat

Heat is a form of energy that has the unit joule (J). Though, in many applied fields the calorie is often used. The standard unit for the rate of heat transmitted is the watt (W), described as one joule per second.

Specific Heat Capacity and Molar Heat Capacity

Molar heat capacity is a calculation of the amount of heat required to increase the temperature of one mole of a pure material by one degree K. Specific heat capacity is a calculation of the amount of heat required to increase the temperature of one gram of a pure material by one degree K.

Specific Latent Heat of Fusion

Specific latent heat of fusion, lf, of a material is described as the amount of heat necessary to change a unit mass of the material from solid to liquid state, without any change in the temperature.

Mechanical Equivalent of Heat

The mechanical equivalent of heat describes that movement and heat are equally exchangeable and that in every case, a specified amount of work would produce the same amount of heat, provided the work done is completely converted to heat energy.

Measurement of Specific Heat

Specific heat capacity is the quantity of heat necessary to increase the temperature of one gram of a material by one degree Celsius. The value of the specific heat of water is represented by 4.184 J/g⋅oC (Joules per gram per degree celsius)

Measurement of Specific Latent Heat of Fusion

In order to calculate the specific latent heat of fusion of ice, a measured quantity of hot water is dispensed into a test-tube. This water, in cooling down to 0°C, gives up an identified amount of heat to the ice, some of which melts. Thus the latent heat of fusion of ice can be calculated.
