Think about putting a glass of water on the counter, in the freezer, and on a hot stove how does the temperature of the water affect the kinetic energy and physical state?

The kinetic energy and the physical state of water depend strongly on the temperature;

Firstly, The kinetic energy of water on a hot stove is higher than that on the counter in the freezer; that the kinetic energy is directly proportional to the temperature according to the relation: ; where R is the universal gas constant, T is the temperature and NA is Avogadro number.

As the temperature increases, the speed of colliding molecules increases and the kinetic energy increases.

Secondly, The physical state of water depends on the temperature; water has three states (gas, liquid and solid) depends on the temperature.If a glass of water is putt on the counter in the freezer, it will be converted to the solid state (ice).And, as if it is putt on a hot stove, it will be vapor (gaseous state).
