Question

Copper has a specific heat capacity of 3.80 x 102 Jkg-1K-1 What temperature

change would 300 g of copper experience when heated with 560 J of thermal
energy?​

Answer 1

4.91 K

Step-by-step explanation:

From the question,

q = cm(Δt)................ Equation 1

Where q = heat, c = specific heat capacity of copper, m = mass of copper, Δt = temperature change.

make Δt the subject of the equation

Δt = q/cm.................. Equation 2

Given: q = 560 J, m = 300 g = 0.3 kg, c = 380 J/kg.K

Substitute these values into equation 2

Δt = 560(0.3×380)

Δt = 560/114

Δt = 4.91 K
