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, measured in Kelvin. If the pressure is 7 lb per square inch when the temperature is 420ºK, find the constant of variation.

49
60
1/49
1/60

Answer 1

P = (k)T
=> 7 = (k)420
=> k = 7/420 = 1/60 = D.
