In a reaction 2.5KJ of heat is released from the system and 5.5 KJ of work is done on the system.Calculate 'DeltaU'.

if work is done by the system then W is

Calculate DeltaU if 2kJ heat is released and 10kJ work is done on the system.

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

In a process, 701 J 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?

Calculate the changes in internal energy of a system if, 300 J of heat energy is added to the system and a work of 160 J is done on the system.

When a system is taken from A to C through path ABC, 10 J of heat flows to the system and 4 J of work is done by the system. How much heat flows into the system in path ADC, if the work done by the system is 3 J ?

A gas can be ken from A to B via two different processes ACB and ADB. When path ACB is used 60 J of heat flows into the system and 30 J of work is done by the system. If path ADB is used work done by the system is 10 J. The heat Flow into the system in path ADB is :

What is the change in internal energy if 10 J of heat is given to system at constant pressure and 20 J of work is done by the system?

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.

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.
