Answer:
c. The heat energy is used to increase the kinetic energy of the molecules, raising the temperature.
Explanation:
When heat is supplied to the molecules of single phase then we can say that thermal energy given to the molecules will definitely increase their internal energy.
But as we know that all the the molecules here are in single phase so the vibrational energy will not exist here
So we will say that heat energy given to the molecules will only increase their kinetic energy due to which the temperature will increase.
So here correct answer will be given as
c. The heat energy is used to increase the kinetic energy of the molecules, raising the temperature.
Option C is correct. The heat energy is used to increase the kinetic energy of the molecules, raising the temperature. This statement describes the changes that molecules undergo.
What is kinetic energy?
The kinetic energy (KE) is defined as the one-half of the mass of each gas molecule times multiplied by the square of RMS velocity.
[tex]\rm KE= \frac{1}{2}mv_{rms}^2[/tex]
where,
KE is the kinetic energy
m is the mass of each molecule
(V)rms is the RMS velocity
When heat is applied to single-phase molecules, we may claim that the thermal energy provided to the molecules will increase their internal energy.
However, because all of the molecules here are in a single phase, vibrational energy will not exist.
As a result, we may conclude that providing heat energy to molecules will only increase their kinetic energy, causing the temperature to rise.
Hence option C is correct.
