Question

Copper has a specific heat of 0.09 cal/g x C . How much change in temperature would the addition of 8373 cal of heat have on a 538.0 gram sample of copper

Answer 1

Answer:

172.92 °C

Explanation:

Concept being tested: Quantity of heat

We are given;

• Specific heat capacity of copper as 0.09 cal/g°C
• Quantity of heat is 8373 calories
• Mass of copper sample as 538.0 g

We are required to calculate the change in temperature.

• In this case we need to know that the amount of heat absorbed or gained by a substance is given by the product of mass, specific heat capacity and change in temperature.

• That is, Q = m × c × ΔT

Therefore, to calculate the change in temperature, ΔT we rearrange the formula;

ΔT = Q ÷ mc

Thus;

ΔT = 8373 cal ÷ (538 g × 0.09 cal/g°C)

    = 172.92 °C

Therefore, the change in temperature will be 172.92 °C
