What is internal energy ?

Define- Internal energy.

The internal energy of a system can be changed by

1.0 kg of liquid water is boiled at 100^@C and all of it is converted to steam. If the change of state takes place at the atmospheric pressure (1.01 xx 10^5 Pa ), calculate the change in the internal energy of the system. Given , the volume of water changes from 1.0 xx 10^-3 m^3 in liquid form to 1.671m^3 when in the form of steam.

The latent heat of vaporization of a liquid at 500 K at1atm pressure is 10 kcal/mol. The change in the internal energy of 3 mole of liquid at same temperature will be

1 g of water at 100^@C is coverted into steam at the same temperature. If the volume of steam is 1671 cm^2 , find the change in the internal energy of the system. Latent heat of steam = 2256 Jg ^-1 . (1 atmosphere pressure = 1.013 xx 10^5 Nm^-2 )
