Two moles of a gas at temperature T and volume V are heated to twice its volume at constant pressure. If `(C _(p))/(C _(v)) = gamma` then increase in internal energy of the gas is-

The Volume of one mole of the gas is changed from V to 2V at constant pressure p. If gamma is the tatio of specific heats of the gas, change in internal energy of the gas is,

The amount of heat required to raise the temperature of a diatomic gas by 1ºC at constant pressure is Q_(p) and at constant volume is Q_(v) . The amount of heat which goes as internal energy of the gas in the two cases is nearly

C_p is always greater than C_v for a gas, which of the following statements provide, partly or wholly, the reason for this? (i) No work is done by a gas at constant volume (ii) When a gas absorbs heat at constant pressure, its volume must change (iii) For the same change in temperature, the internal energy of a gas changes by a smaller amount at constant volume that at constant pressure (iv) The internal energy of an ideal gas is a function only of its temperature

C_p is always greater than C_v for a gas, which of the following statements provide, partly or wholly, the reason for this? (i) No work is done by a gas at constant volume (ii) When a gas absorbs heat at constant pressure, its volume must change (iii) For the same change in temperature, the internal energy of a gas changes by a smaller amount at constant volume that at constant pressure (iv) The internal energy of an ideal gas is a function only of its temperature

One mole of an ideal gas at pressure P_(0) and temperature T_(0) is expanded isothermally to twice its volume and then compressed at constant pressure to (V_(0) // 2) and the gas is brought bac to original state by a process in which P alpha V (pressure is directly proportional to volume). The correct temperature of the process is

Aperfect gas at 27^(@) C is heated at constant pressure soas to duuble its volume. The increase in temperature of the gas will be

Aperfect gas at 27^(@) C is heated at constant pressure soas to duuble its volume. The increase in temperature of the gas will be

The temperature of a gas at pressure P and volume V is 27^(@) C . Keeping its volume constant if its temperature is raised to 927^(@) C , then its pressure will be
