Which is an example of the kinetic-molecular theory not holding true for a gas? a. the average kinetic energy of particles depends only on the temperature. b. the particles in a gas travel in straight lines in a continuous, random motion. c. the attraction between particles causes a gas to condense at low temperatures. d. the particles in a gas make up a small portion of the total volume of the gas.

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.
