Phase Transition

we can use conservation of energy to determine how much energy is needed to change a solid to a liquid, and a liquid to a gas.

When food is in its solid state it has the least amount of potential energy.

When we melt the food we have to put thermal energy into the system to induce a phase change

since we are converting thermal energy into kinetic energy we expect the food to start moving.

While the food will not start moving around, the molecules inside the food will start moving
