d. 60

Step-by-step explanation:

According to Gay Lussac's Law

P1/T1=P2/T2 where

P1 = Pressure at the start, T1 = initial Temperature

, P2 = Final Pressure, T2 = Final Temperature

T1=P1*T2/P2 = 7*420/49=60

An enclosed gas exerts a pressure P on the walls of the container. this pressure is directly proportional to the temperature T of the gas. if the pressure is 7 lb per inch squared when the temp is 420°F, find the constant of variation.a. 1/49b. 49c. 1/60d. 60
