The value of the product of a universal gas constant and the temperature difference is given by 10 kJ/mol at 1 mole and the internal energy is given by 20 KJ, what is the enthalpy of this system in KJ?

Thermodynamics is used in heating and cooling systems (heat pumps, rerigerator, etc.) in our homes and other buildings, engines that power our motor vehicles, even the design of buildings and vehicles.
