Change in internal energy of a thermodynatic system is called heat of reaction at contant

Change in internal energy of a system is

(i) Show that heat of reaction at constant volume is equal to the change in internal energy of the system. (ii) Show that heat of reaction at constant pressure is equal to the change in enthalpy of the system.

The change in internaL energy of a system depends on

Calculate the changes in internal energy of a system if, 400 calorie of heat energy are added to the system and the system does 500 calories of work on the surroundings.

Calculate the changes in internal energy of a system if, 400 calorie of heat energy are added to the system and the system does 500 calories of work on the surroundings.

What is the relation between change in internal energy of the system and heat energy supplied to the system or heat extracted from the system?

If change in internal energy -90 J. The work done by system is + 50 J. Calculate the heat change.

The internal energy of a system can be changed by

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.

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.
