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)

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

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 1500 joule of energy as heat and produces 500 joule of work .the change in internal energy of the system will be :

A system loses 120 ) of heat and does 80 J of work. Calculate the change in 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 50 kJ heat and does 20 kJ of work. What is the net change in the internal energy of the system ?

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
