A piston exering a pressure of one atm rests on the surface of water at `373K`. The pressure is reduced to smaller extent and as a result `10gm` of water evaporates and absorbs `22.4kJ` of heat. The change in internal energy is `:`

A pistion exerting a pressure of 1.0atm rests on the surface of water at 100^(@)C . The pressure is reduced to smaller extent and as a result 10g of H_(2)O eveportes and abosrb 20 kJ fo heat. Determine

One mole of SO_(2) at 298K and 1atm pressure is heated in a closed vessel so that its temperature is 475K and pressure is 4atm . It is then cooled so that temperature becomes 298K and pressure is 1atm . What is that change in the internal energy of the gas?

A gas absorbs 100 calories of heat energy and is compressed from 10.0 L to 5.0 L by applying an external pressure of 2.0atm. The change in internal energy is

5.00 kg of liquid water is heated to 100. 0^@ C in a closed system At this temperature , the density of liquid water is 958 kg/ m^3 . The pressure is maintained at atmospheric pressure of 1.01 xx 10^5 Pa. A moveable piston of negligible weight rests on the surface of the water. The water is then converted to steam by adding an additional amount of heat to the system. When all of the water is converted, the final volume of the steam is 8.50 m^3 . The latent heat of vaporization of water is 2.26 xx 10^6 J/kg. What is the change in the internal energy during this isothermal process?
