levacccp [35]

Answer:

Lead

Explanation:

The material that will warm up the fastest would be<u> lead.</u>

<em>The specific heat capacity of a substance is the amount of heat required to raise the temperature of a unit of the substance by one degree. The higher the specific heat capacity of a substance, the higher the amount of heat required to raise the temperature of the substance and vice versa.</em>

The specific heat capacity (in J/g °C) of granite, iron, copper, and lead are as follows:

Granite - 0.790

Iron    - 0.450

Copper - 0.385

Lead - 0.129

From the table, <u>lead has the lowest specific heat capacity, hence, it will be the fastest to get warmed when equal masses of all the substances are placed in the sunlight.</u>
