Answer:

c = 0.376/.c

Step-by-step explanation:

To find the specific heat of copper, we can use the formula:

q = mcΔT

Where:

q = amount of heat energy (in joules)

m = mass of the substance (in grams)

c = specific heat capacity of the substance (in J/g°C)

ΔT = change in temperature (in °C)

We are given:

q = 242.2 J

m = 81.6 g

ΔT = (35.2 - 27.5) °C = 7.7 °C

Plugging in the values into the formula, we have:

242.2 J = (81.6 g) * c * 7.7 °C

To solve for c, we can rearrange the equation:

c = 242.2 J / (81.6 g * 7.7 °C)

c = 0.376 J/g°C

Therefore, the specific heat of copper is 0.376 J/g°C.
