Kinetic particle model of matter — practice question

Pot X and pot Y are both placed in a cool room. Pot X contains hot water, but its temperature is still below the boiling point. Pot Y is identical to pot X except that its water is kept boiling by a hotplate underneath it. What happens to the average kinetic energy of the particles in the liquid water in pot X and to the average kinetic energy of the particles in the liquid water in pot Y?

  • AX: decreases, Y: increases
  • BX: decreases, Y: does not change
  • CX: stays the same, Y: increases
  • DX: stays the same, Y: does not change
