Using Gay-Lussac's Law, calculate what the new pressure in the following situation. A tank of acetylene sits on the back of a truck. During the afternoon, the temperature
of a gas has reached 38°C (311 K) with a pressure of 508 kPa. That night, the
temperature drops to 29°C (302 K). Since the gas was in a metal tank, the volume
remained constant. What is the new pressure?
311 kPa
500 kPa
503 kPa

308 kPa
