What causes beads of moisture to form on the outside of a cold drinking glass? a. water vapor in the air gains thermal energy from the cold glass surface. b. water vapor in the air condenses into a liquid on the cold glass surface. c. the melting ice in the drink causes some liquid to spill over. d. water vapor in the air has less thermal energy than water in the glass.

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.
