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.
<h3>What is average kinetic energy?</h3>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.
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.

Answer:
C ) 1500 Joules
Explanation:
In the attached image, we can see how the box was moved 10 meters by the force of 150 N.
The definition of work is W = F * d
therefore
W= 150*10 = 1500 J
