Three kg of saturated liquid water are evaporated at $60$C$.$

a$.$ At what pressure will this occur at equilibrium?

b$.$ What is the initial volume?

c$.$ What is the system volume when $2$ kg have evaporated? At this point, what is $$U

relative to the initial state?

d$.$ What are $$H and $$U relative to the initial state for the process when all $3$ kg have

been evaporated?

e$.$ Make a qualitative sketch of parts b$$d on a Pvm diagram, labeling the states before,

during, and after evaporation
