Answer to Question 1

ANS: D
Liquids exhibit flow and assume the shape of their container. Liquids also exert pressure, which varies with depth and density. Variations in liquid pressure within a container produce an upward supporting force, called buoyancy.

Answer to Question 2

ANS: A
During condensation, a gas turns back into a liquid.
