A sample of gas absorbs 4000 kJ of heat. If volume remains constant, what is `DeltaU`?

A sample of gas absorbs 4000 kj of heat (a) if volume remains constant what is DeltaU ? (b) Suppose that in addition to absorption of heat by thesample, the surrounding does 200 kj of work on the sample.What is DeltaU ? (c) Suppose that as the original sample absorbs heat, it expands against atmospheric pressure and does 600 kj of work, on its surroundings. What is DeltaU ?

A sample of gas absorbs 4000 kJ of heat. Suppose that in addition to absorption of heat by the sample, the surroundings, does 2000 J of work on the sample, what is DeltaU ?

A gas of 0.320 kJ works on its surroundings and absorbs 120 J of heat from the surroundings. Hence, DeltaU is

A system absorbs 920 J of heat and does work. The change in internal energy (DeltaU) for the process is 460 J. The work done by the system is ________ .

A gas absorbs 250J of heat and expands from 1 litre to 10 litre at constant temperature against external pressure of 0.5atm. The values of q, w and DeltaU will be respectively

A system absorbs 10 kJ of heat at constant pressure and its temperature rises from 27^@C to 37^@C in vacuum. The DeltaU of reaction is

If 1200 calories of heat is removed from a gas which is held at constant volume, what is the change in internal energy of the system?

5 KL of work is done on the system and it releases 10 kJ of heat. What is DeltaU ?

When the temperature of 5 mol of a gas is changed from 100^@C to 120^@C keeping the volume constant, the change in internal energy of the gas is 80 J, then find the heat capacity of the gas at constant volume.

The specific heat of a gas at constant volume is 20J/mol ^@K . When two moles of such gas is heated through 10^@C at constant pressure, what is the increase in internal energy and work done ? (R= 8J/mol ^@ K)
