Question

In which of these samples do the molecules most likely have the most kinetic energy? (2 points)
A. solid ice at -5°C
B. ice water at 0°C
C. liquid water at 98°C
D.water vapor at 150°C

Answer 1

D, water vapor. Gaseous state would have more kinetic energy, they are moving faster. If you have to compare the same state, then higher temperature would have the higher kinetic energy. But if you have solid and liquid at the same temperature - then liquid would have more.
