Theresa Alvarado · Answer 1

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.
