Question 3

During a test, two aluminium heat sinks X and Y are warmed without changing state. Heat sink X has a mass of 0.40 kg and its temperature rises by 15 ∘C15\ ^\circ\mathrm{C}15 ∘C. Heat sink Y has a mass of 0.60 kg and its temperature rises by 20 ∘C20\ ^\circ\mathrm{C}20 ∘C. Use ΔQ=mcΔθ\Delta Q=mc\Delta\thetaΔQ=mcΔθ.

What is the ratio of the energy absorbed by X to the energy absorbed by Y?
