Answer to Question 1

ANS: D
When the atmospheric pressure is maintained at 49.7 atm, at a temperature of 119 C (oxygen's critical temperature), oxygen maintains an equal balance between its liquid and gaseous states.

Answer to Question 2

ANS: B
The direct change of state from solid to gas is called sublimation. Evaporation involves change from liquid to gas. Latent heat involves a change of state in matter of any form.
