Answer:
C
Explanation:
The increase in the distance between equilibrium positions for the vibrating atoms.
By increasing the distance between equilibrium positions for the vibrating atoms.
• The tendency of matter to change its area, shape, density, and volume in response to a change in temperature is termed as thermal expansion.
• The thermal expansion of a solid can result by enhancing the distance between the equilibrium positions for the vibrating atoms.
• With the supply of thermal energy, the amplitude of the vibration of the atoms enhances. Thus, post providing some heat energy, the distance between the equilibrium positions for the vibrating atoms enhances.
Thus, the correct statement is option c.
