Answer: Option (b) is the correct answer.
Explanation:
When the cake is baked then due to the heat provided to it there will occur movement of its molecules.
As a result, molecules will gain kinetic energy due to which there will occur collisions between them.
Also,
Hence, more is the heat provided to the cake more will be the kinetic energy of its molecules due to which when we touch it, it feels hot.
Thus, we can conclude that molecules in the cake are moving faster than molecules in the skin, best explains why the cake feels hot.
