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

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

Find the change in internal energy if heat supplied to the gaseous system is 100 J and work done by the system is 80 J.

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 .

A system does 200 J of work and at the same time absorbs 150 J of heat. The magnitude of the change in internal energy is __________ J. (Nearest integer)

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.

When a system goes from state A to state B, it is supplied with 400 J of heat and it does 100 J of work. (a) For this transition, what is the system's change in internal energy? (b) If the system moves from B to A, what is the change in internal energy? (c) If in moving from A to B along a different path in which W_(AB)^'=400J of work is done on the system, how much heat does it absorb?

A system absorbs 640 J heat and does work of 260 J, the change in internal energy of the system will be :

A system is provided 50 joule of heat and the change in internal energy during the process is 60 J . Magnitude of work done on the system is:
