A system is given 300 calories of heat and it does 600 joules of work. How much does the internal energy of the system change in this process (J=4.18 "joules"//cal)

A system is given 300 calories of heat and it does 600 joules of work. How much does the internal energy of the system change in this process (j=4.18joules/cal)

A system absorbs 10 kJ of heat and does 4 kJ of work. The internal energy of the system

A system absorbs 10 kJ of heat and does 4 kJ of work. The internal energy of the system

A system absorbs 50 kJ heat and does 20 kJ of work. What is the net change in the internal energy of the system ?

A system absorbs 20kJ heat and also does 10kJ of work. The net internal enegry of the system

A system absorbs 10 kJ of heat and does 4 kJ of work the internal energy

To a system 300 joules od heat is given and it does 60 joules of work. How much does the internal energy of the system change in this process? (in joule)

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

A system absorbs reversibly 600 J of heat and performs 250 J of work. The increase in the internal energy of system is :-
