In a particular reaction the system absorbs 12kJ of heat and does 3kJ of work on its surroundings. What are changes in internal energy and enthalpy of system?

A gas contained in a cyclinder fitted with a frictionless piston expands against a constant external pressure of 1 atm from a volume of 5 litres to a volume of 10 litres. In doing so it absorbs 400 J of thermal energy from its surrounding .Determine the change in internal energy of system.

In a reversible isothermal process, the change in internal energy is

A system is provided 50 joule of heat and work done on the system is10 J. The change in internal energy during the process is

In a thermodynamic process , pressure of a fixed mass of a gas is changed in such a manner that the gas releases 20J of heat and 8J of work is done on the gas. If the initial internal energy of the gas was 30J . The final internal energy will be

A system releases 125 kj of heat while 104 kj of work done on the system. Calculate the change in internal energy.

104 kj of work is done on certain volume of a gas. If the gas releases 125 kj of heat, calculate the change in internal energy (in kj) of the gas.
