Question

An enclosed gas exerts a pressure P on the walls of a container. This pressure is directly proportional to the temperature T of the gas. If the pressure is 7 lb per square inch. when the temperature is 420ºF, find the constant of variation.

Answer 1

7 = 420 k

k = 1 / 60

Explanation:

Answer 2

420 F must be converted to degrees absolute
= 420+460 = 880 degrees absolute
P = kT
7 = k * 880
k = 7/880p = K T

7 = 420 k

k = 1 / 60
