Potential energy<span> is energy which results from position or configuration. It is the energy stored in an object not moving. It is calculated by:
PE = mgh
where m is the mass, g is the gravitational acceleratin and h is the height.
PE = 10 ( 9.8) (320) = 31360 J = </span>3.1 x 104 J --------> OPTION 2

When a material in liquid state is given energy, it changes its phase from liquid to vapor; the energy absorbed in this process is called heat of vaporization. The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol. The vaporization is the opposite process of condensation.
