Answer to Question 1

ANS: D
The pressure exerted by a liquid depends on both its height (depth) and weight density (weight per unit volume), which is shown in equation form:
PL = h  dw.

Answer to Question 2

ANS: D
Conduction is the transfer of heat by direct contact between hot and cold molecules.
