The phase diagram of Argon is shown below. Argon has two distinct solid phases α and β. When the solid-α to solid-β phase transition occurs, heat is given off.
a) Label the sections of the phase diagram with the appropriate phases

b) Which has a higher density solid-α or solid β?
c) Can solid-α undergo sublimation? Explain your answer.
d) Which solid can be obtained by cooling a sample of gas at atmospheric pressure?
