0.32 g of oxygen is kept in a rigid container and is heated. Find the amount of heat needed to raise the temperature from 25^0 C to 35^0 C . The molar heat capacity of oxygen at constant volume is 20 J K^(-1) mol^(-1) .

The molar heat capacity of oxygen gas at STP is nearly 2.5R. As the temperature is increased, it gradually increases and approaches 3.5 R. The most appropriate reason for this behaviour is that at high temperature

Calculate the amount of heat absorbed by 100 g of ice to change into water of 30^(@)C . (Specific heat capacity of water is 1 cal//g^(@)C )

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.

True or False: The specific heat capacity of water is 1.0 cal//g^(@)C
