Question

Calculate the specific heat of copper, given that 204.75 J of energy raises the temperature of 15 g of copper from 35°C to 70°C. Remember the formula for changes in temperature heat calculations is q = MCΔT.

A. 0.096 J/g°C
B. 0.256 J/g°C
C. 0.138 J/g°C
D. 0.321 J/g°C

Answer 1

The specific heat of copper is 0.138 J/g°C.

Step-by-step explanation:

The specific heat of a substance can be calculated using the formula q = MCΔT, where q is the amount of heat transferred, M is the mass of the substance, C is the specific heat, and ΔT is the change in temperature. In this case, we are given that 204.75 J of energy raises the temperature of 15 g of copper from 35°C to 70°C. So, the equation becomes 204.75 J = 15 g * C * (70°C -35°C). Solving for C, we get C = 0.138 J/g°C. The specific heat of copper is calculated using the formula q = mcΔT with the provided values, resulting in a specific heat of 0.390 J/g°C.

Therefore, the specific heat of copper is 0.138 J/g°C, which corresponds to option
