Which sample is most likely to undergo the smallest change in temperature upon the absorption of 100 kj of heat?

50 g of Water sample is most likely to undergo the smallest change in the temperature on the absorption of 100 kJ of heat.

Explanation:

Specific heat is the energy required to raise the temperature of 1 kg of a substance by 1-degree Celcius.

The substance that has a high specific heat will require less amount of energy to change the temperature.

Water is said to have high specific heat, as compared to other materials. Since it already has a high specific heat to raise or change the temperature to a small extent, a small amount of specific heat is enough.

The higher the mass, the higher will be the specific heat for the substance.

Among, 15 g water

15 g Lead

50 g Water

50 g Lead

50 g water undergoes the smallest change.
