You cool a hot piece of iron by dropping it in cool water. Which statement incorrectly describes what is happening? a) after enough time, the final temperature of the water and iron will be the same
b) the amount of heat gained by the water equals the amount of heat lost by the iron
c) the temperature of the iron will decrease as the temperature of the water increases
d) the temperature change of the iron will depend on the latent heat of iron

Answer :

Answer:

Option d. The temperature change of iron will depend on its latent heat

Explanation:

If the Calorimetry Principle is taken into consideration which says that in case of no heat loss in the surrounding then the reduction in total amount of heat of a hot body is the same as the rise in the total heat of the cold body.

Therefore, iron's temperature change will not depend on its latent heat and will depend on the the other three mentioned factors:

  • The resulting temperature of iron and water will be equal
  • Rise in heat of water equals to the amount of heat reduced or heat loss by the iron.
  • Decrease in temperature of water will result in an equivalent increase in temperature of iron.
