Heat
In the unending search of the man for new source of energy,
around the end of seventeenth century he learn to convert heat
energy into mechanical energy.
Water when heated is converted into steam. Since steam
occupies a large volume than that occupies by the same amount of
water, it exerts a greater pressure on the walls of the
container. This steam can now be used to move objects to do
mechanical work.
