Question

Assuming all the substances below have the same mass, which substance below requires the least energy to raise its temperature by 7oC? Use the table to help you answer the question.
A.Water
B.Gold
C.Aluminum
D.Wood

Answer 1

Answer:

The correct answer is D.

Explanation:

The specific heat, or also called specific heat capacity, is the energy needed to raise the temperature of 1 kg of mass by 1 degree Celsius. If we know that all the substances have the same mass, the facility to increase in 7 ºC will depend on the lower value of the specific heat. In this way, the element that requires less energy to increase 7 ºC is wood.

Have a nice day!
