Question

If two glasses of water are at the same temperature, the average kinetic energy of the particles of water in each glass is the same. Please select the best answer from the choices provided T F

Answer 1

The statement ‘If two glasses of water are at the same temperature, the average kinetic energy of the particles of water in each glass is the same’ is true. This is because temperature is directly proportional with the kinetic energy of the molecules. If there is no change in temperature, there would not be kinetic movement of the molecules.

Answer 2

Answer: The correct answer is True.

Explanation:

Average kinetic energy of the particles is defined as the average of the kinetic energies of the particles present in a medium. It is the measure of temperature of the medium.

Mathematically,

$K=\frac{3}{2}\frac{RT}{N_A}$

where,

K = kinetic energy

T = Temperature

$\text{Kinetic energy}\propto \text{Temperature}$

As, kinetic energy of the particles is directly proportional to the temperature. Increase in temperature will result in the increase in the kinetic energy and vice-versa.

We are given, that the temperature of the two glasses are same, so the average kinetic energy of the particles will also remain same.

Hence, the correct answer is True.
