Use the phase diagram for H2O to answer the following questions. a. What phase is water in at 100°C and 2 atm pressure? (1 point)

b. What happens to water at 100°C as pressure is increased from 0.8 atm to 1.2 atm? (1 point)

c. What happens to water at 1 atm pressure as the temperature is decreased from 10°C to –10°C? (1 point)

d. What line represents boiling points on a phase diagram? (You may describe it or label it on the phase diagram.) (1 point)

e. How do intermolecular forces and kinetic energy interact to determine at what point a liquid will boil? (2 points)
