Delgado · Answer 1

How much a substance increase its temperature due to heat transfer depends on its specific heat.

The specific heat is the amount of heat required to increase the temperature of one mass of substance in 1 °Celsius.

The lower the specific heat the more the substance change its temperature with a given amount of heat, the greater the specific heat of the substance the lesser the change of temperature with the same amount of heat.

Then, to predict which of the two blocks will have the greater rise you need to compare the specific heats of the metals.

From tables, the specific heat of gold is 0.129 J/g°C and specific heat of iron is 0.450J/g*°C.

Then, gold will raise more its temperature than iron, after the addition of the same amount of heat.
