Question

Two pieces of metal with exactly the same mass are placed on a surface in bright sunlight. The temperature of the 1st block increases by 3°C while the temperature of the 2nd increases by 8°C. If the specific heat of the 2nd block is 0.24 J/g-K, what is the specific heat of the 1st block?

Answer 1

Answer:

0.64 J/g-K

Explanation:

Solving this question relies on the relization that both blocks receive the same amount of energy but of course their temperature cannot rise by the same amount even if you had the same mass of both because they have different specific heat capacities.

amount of energy received by block 1 = amount of energy received by block 2

specific heat of block 1 * ΔT of block 1 = specific of  block 2 * ΔT of block 2

C * 3 = 0.24 * 8

C = 0.64 J/g-K
