Web9. The process of liquid water at 0°C turning to solid water, ice, is an exothermic process. Thermal energy is the sum of the kinetic and potential energy. As thermal energy is taken away from the system—liquid water, the kinetic energy of the water molecules decreases, making the molecules move slower, so the temperature of water decreases. WebMomentum is simply mass times velocity, while kinetic energy is one half of the product of the mass and the square of the velocity. So when we look at the simple mode and mean of the Maxwell-Boltzmann distribution (which …
