Specific heat capacity

Text Solution

Verified by Experts

(i) The amount of heat energy required to raise the temperature of unit mass of substance through `1^(@)C` is called specific heat capacity.
(ii) 'm' is a mass of and object which has specific heat capacity of 'c'. If its temperature is to be increased by `DeltaT` then the heat abosrbed by a substance can be calculated as ,
Heast absorbed `= mc DeltaT` .......`DeltaT` is rise in temperature .
(iii) If the temperature of a substance in reducedm, then heat lost by a substance can be given as
Heat lost ` = mcDelta T` .........`DeltaT` is fall in temperature .
`therefore ` Specific heat capacity is necessary to find amount of heat loss or gain.

An experiment is performed to measure the molar heat capacity of a gas at constant pressure using Regnault's method. The gas is initially contained in a cubical reservoir of size 40 cm xx 40 cm xx 40 cm xx at 600 kPa at 27^0C . A part of the gas is brought out, heated to 100^0C and is passed through a calorimeter at constant pressure. The water equivalent of the calorimeter and its contents increases from 20^0C to 30^0C during the experiment and the pressure in the reservoir decresases to 525 kPa . Specific heat capacity of water = 4200 J kg^(-1) K^(1). Calculate the molar heat capacity Cp from these data.
