During compression of a spring the work done is 10 kJ and 2 kJ escaped to the surroundings as heat. The change in internal energy, Delta U (in kJ) is _________ .
During 200J work done on the system, 140J of heat is given out. Calculate the change in internal energy.
A system absorbs 6 kJ of heat and does 1.5 kJ of work on its surroundings. The charge in internal energy is ………
A certain electric motor produced 15 kJ of energy each second as numerical work and lost 2kJ as heat to the surroundings. What is the change in the internal energy of the motor and its power supply each second.
A gas performs 0.320 kJ work on surroundings and absorbs 120 J of heat from the surroundings.Hence change in internal energy is
A certain electric motor produced 16kJ of energy each second as mechanical work and lost 3kJ as heat to the surroundings. What is the change in the internal energy of the motor and its power supply each second?
During a process ideal gas expands to compress the spring such that 10kJ energy is stored in the spring and 2kJ heat is released from gas to surrounding find the change in internal energy of gas
