A system is given 400 calories of heat and 1000 Joule of work is done by the system, then the change in internal energy of the system will be

Heat given to a system is 30 joules and work done by the system is 15 joules. The change in the internal energy of the system will be

Heat given to a system is 35 joules and work done by the system is 15 joules. The change in the internal energy of the system will be

Heat given to a system is 35 joules and work done by the system is 15 joules. The change in the internal energy of the system will be

A system is provided with 50 J of heat and the work done on the system is 10J .What is the change in internal energy of the system in joules ?

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.
