Find the change in internal energy (in joule) of a gas when it absorbs `40 calories` of heat and performs work equal to `16 J`.

Find the change in internal energy of a gas when (i) it absorbs 80 calorie of heat and performs work equal to 170 Joule (ii) it absorbs 20 calorie of heat and work equal to 55 Joule is performed on it.

Find the change in internal energy of the system when a system absorbs 2 kilocalorie of heat and at the same time does 500 joule of work

Calculate the change in internal energy of a system which absorbs 100 J of heat and does 215 J of work.

Calculate the change in the internal energy of a system which absorbs '500 J' of heat, and does work equivalent to '200 J' on the surroundigs.

Find the magnitude of change in internal energy when system does 150J work and absorbs 200J heat

Calculate the change in internal energy if the work done by the system be 8 joule when 40 joule of heat is given to it.

If change in internal energy -80 J. The work done by system is +40 J. Calculate the heat change.

If change in internal energy -80 J. The work done by system is +40 J. Calculate the heat change.

For a gaseous system find change in internal energy if the heat supplied to the system is 50 J and work done by the system is 16 J.
