An ideal gas expand against a constant external pressure at 2.0 atmosphere from 20 litre to 40 litre and absorb `10kJ` of energy from surrounding . What is the change in internal energy of the system ?
A
4052 J
B
5948 J
C
14052 J
D
9940 J

The correct Answer is:
B
`DeltaU=q+w` `=10 xx 1000 -2 xx (20)xx101.3 = 5948 J`

A system absorbs 50 kJ heat and does 20 kJ of work. What is the net change in the internal energy of the system ?
A simple of gas present in a cylinder fitted with a frictionless piston expands against constant pressure of 1atm from a volume fo 2L to 12L . During the process, it absorbs 600J of heat from the surroundings. Calculate the change in internal energy of the system.
Frictionless and weightless piston was fitted into a cylinder containing a gas This gas was allowed to expand from one litre to 5 litre against a constant pressure of one atmosphere in doing so, 200 J of heat was absorbed from the surrounding . The change in the internal energy of the system is :
A gas performs 0.320 kJ work on surroundings and absorbs 120 J of heat from the surroundings.Hence change in internal energy is
A gas contained in a cylinder fitted with a frictionless piston expands against a constant pressure 1 atmosphere from a volume of 4 litre to a volume of 14 litre. In doing so, it absorbs 800 J thermal energy from surroundings. Determine DeltaU for the process.
A gas expands against a constant external pressure so that the work done is 607.8 J . The work done in litre atmosphere is
