2. An enclosed gas exerts a pressure P on the walls of its container.

This pressure is directly proportional to the temperature T of the gas.

If the pressure is 4 pounds per square inch when the temperature is 480° K,

identify the appropriate direct variation equation.

$\displaystyle A)\; P = \frac{1}{120}T\qquad B)\;P= \frac{1}{16}T\qquad C)\;$$\displaystyle P = 16T\qquad D)\; P= 120T$
