Question

Since temperature increases when the average kinetic energy of particles increases, what is happening to the added energy when the temperature remains constant while a substance is melting or boiling?.

Answer 1

Latent heat is the heat required to change the phase. When the temperature remains constant during melting or boiling the added energy is employed in the phase change process.

What is average kinetic energy?

The average kinetic energy (KE) is defined as the one-half of the mass of each gas molecule times multiplied by the square of RMS velocity.

$KE = \frac{1}{2}m (V_{rms})^{2}$

where,

KE is the kinetic energy

m is the mass of each molecule

(V)rms is the RMS velocity

As we know since the temperature is increasing the average kinetic energy of the particle increases. So the added energy is utilized in the sensible heat due to which the temperature of the body increases resulting in the increase in average kinetic energy

But when the temperature remains constant during melting or boiling the added energy is converted into latent heat energy utilized to convert the phase of a substance.
