Some small aluminium rivets of total mass 170g and
at 100°C are emptied into a hole in a large block of
ice at 0°C
a What will be the final temperature of the rivets?
b How much ice will melt?

9.98 kg of r-134a at 300 kpa fills a rigid container whose volume is 14 l. determine the temperature and total enthalpy in the container. the container is now heated until the pressure is 600 kpa. determine the temperature and total enthalpy when the heating is completed. use data from the steam tables.
