What does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the molecules decreased kinetic energy of the molecules increased chemical energy of the molecules increased kinetic energy of the molecules how does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k. the helium at 15 â°c has lower nuclear energy than the sample at 215 k. the helium at 15 â°c has slower-moving atoms than the sample at 215 k. the helium at 15 â°c has smaller atoms than the sample at 215 k.
