Question

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?

Answer 1

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: $K = \frac{3RT}{2NA}$ ; 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).
