0.056 kg of Nitrogen is enclosed in a vessel at a temperature of `127^@C` . The amount of heat required to double the speed of its molecules is ______k cal.
(Take R = 2 cal `"mole"^(-1) K^(-1)` )

About 0.014 kg nitrogen is enclosed in a vessel at temperature of 27^(@)C How much heat has to be transferred to the gas to double the rms speed of its molecules ? (R = 2 cal//mol K)

The mass 15 gram of Nitrogen is enclosed in vessel at 300K. What heat must be supplies to it to double the 'rms' velocity of its molecules

14 g of nitrogen is contained in a vessel at 300 K. How much heat should be taken out of the gas to half the rms speed cf its molecules ? R=2 cal/mol K:

Amount of heat energy required to raise the temperature of 2 g neon gas by 54°F at constant volume is (R= 2 cal mol^-1 K^-1 )

A mass M = 15 g of nitrogen is enclosed in a vessel at temperature T = 300 K. What amount of heat has to be transferred to the gas to increase the root-mean-square velocity of molecules 2 times ?

The amount of heat required to raise the temperature of 1 kg of water 1^(@)K at constant pressure is

Certain amount of heat is given to 100 g of copper to increase its temperature by 21^@C . If same amount of heat is given to 50 g of water, then the rise in its temperature is (specific heat capacity of copper = 400 J kg^(-1) K^(-1) and that for water = 4200 J kg^(-1) K^(-1))

Forty calories of heat is needed to raise the temperature of 1 mol of an ideal monatomic gas from 20^(@)C to 30^(@)C at a constant pressure. The amount of heat required to raise its temperature over the same interval at a constant volume (R = 2 cal mol^(-1) K^(-1)) is
