2 kg of air is heated at constant volume. The temperature of air is increased from 293 K to 313K. If the specific heat of air at constant volume is `0.718 k. j//kg K`, find the amount of heat absorbed in kj and kcal (`J=4.2 KJ// Kcal)`

Five kg of air is heated at constant volume. The temperature of air increase from 300K to 340K. If the specific heat at constant volume is 0.169 kcal/kg K, find the amount of heat absorbed.

Five kilomoles of oxygen is heated at constant pressure. The temperature of the oxygen gas is increased from 295K to 305K. If the molar heat capacity of oxygen at constant pressure is 6.994 kcal/kmole K. The amount of heat absorbed is in kcal,

The specific heat of air at constant pressure is 1.005 kJ/kg k and the specific heat of air at constant volume is 0.718 kJ/kgK. Find the specific gas constant
