Difference Between Conduction, Convection and Radiation:
While conduction is the transfer of heat energy by direct contact, convection is the movement of heat by actual motion of matter; radiation is the transfer of energy with the help of electromagnetic waves.
So I would agree with C. Radiation can move through empty space, whereas conduction and convection require matter to transfer heat (by movement or direct contact).
Answer:
a for the first one b for the second
The statement that can be used to answer this question is:
"If the cylinder is brought higher then, its temperature when brought down becomes higher because a greater amount of potential energy is converted to thermal energy."
The potential energy is converted to thermal energy when the object is released the velocity becomes higher because of the acceleration due to gravity.

Answer:
Explanation:
We have acceleration given by
Velocity at t = 0
Velocity is given by
at t = 0
The equation will be
