Answer:

Change in temperature (Δt) = 18.18°C (Approx.)

Explanation:

Given:

Mass of metal block (M) = 55g

Specific heat of metal (c) = 0.45 J/g°C

Amount of energy added (Q) = 450 J

Find:

Change in temperature (Δt)

Computation:

Using Specific Heat Energy formula

Q = McΔt

450 = (55)(0.45)(Δt)

450 = (24.75)(Δt)

Change in temperature (Δt) = 450 / 24.75

Change in temperature (Δt) = 18.18°C (Approx.)
