In which of these samples do the molecules have the greatest kinetic energy? (3 points) Question 2 options: 1) solid ice (-25 °C) 2) water vapor (102°C) 3) ice water (0°C) 4) liquid water (54°C)
Kinetic energy is the energy in motion. The higher the temperature, the higher the motion of molecules. Therefore from the choices, water vapor at 102C has the highest kinetic energy.
