A system absorbs 115J heat from the surroundings and 290 J work is done on the system calculate the change in internal energy of the system.

Change in internal energy of a system is

In a process, 600 J of heat is absorbed by asystem and 300 J of work is done by the system. Calculate the change in internal energy of the system.

In a process, 600J of heat is absorbed by a system and 300J of work is done by the system. Calculate the change in internal energy of the system.

Give examples of three processes in which the change in internal energy of the system is zero.

In a process, 701J of heat is absorbed by a system and 394 J of work is done by the system. What is the change in internal energy for the process?

In a certain process. 678 J of heat is absorbed by a system, while 294 J of work is done on the system. What is the change in the internal energy for the process?

A gas confined in a cylinder with a frictionless piston is made to expand from 1L to 5L under constant pressure of 1.5 atm. During the process, 800J of heat is supplied from external source. Calculate the change in internal energy off the gas. (1L*atm=101.3J) .
