(a) State the three different types of heat transfer, and give a simple example for each type of heat transfer.
(b) Calculate the amount of heat required to change of ice in a sealed container of volume
and pressure at
at
to steam at
. (Neglect the heat absorbed by the air and the container. The specific heat of ice and steam is
). What is the pressure inside the container expressed in atmospheric pressure, when the
of ice is completely changed to steam at
?
Roughwork.
(a) Skip it.
(b) Stuck. Any equation of state as may well be applicable to solids and liquids as the ideal gas law
to gases, lacking the enthalpies of fusion and vaporisation unknown?
