If I initially have a gas at a pressure of 824 mm Hg, a volume of 21.3 L and a temperature of 293.0 K, then I raise the pressure to 921.9 mm Hg and increase the temperature to 25.62 degrees C. What is the new volume of the gas in L.​

How does a sample of helium at 15 degree celsius compare to a sample of helium at 215 k? a) the helium at 15 degrees celsius has a higher average kinetic energy that the sample at 215 k. b) the helium at 15 degrees celsius has lower nuclear energy that the sample at 215 k. c) the helium at 15 degrees celsius has slower- moving atoms that the sample at 215 k. d) the helium at 15 degrees celsius has smaller atoms than the sample at 215 k.
