How many degrees can 510 g of copper be heated if you use the same amount of heat

How many degrees can 510 g of copper be heated if you use the same amount of heat that is released during cooling of 2 liters of oil at 40 degrees Celsius.

Given: m1 (mass of copper) = 510 g = 0.51 kg; V2 (oil volume) = 2 l = 0.002 m3; Δt2 (change in sunflower oil temperature) = 40 ºС.

Constants: C1 (specific heat capacity of copper) = 370 J / (kg * ºС); ρ2 (oil density) = 930 kg / m3; С2 (specific heat capacity of sunflower oil) = 1700 J / (kg * ºС).

1) Heat during cooling of sunflower oil: Q = C2 * m2 * Δt2 = C2 * ρ2 * V2 * Δt2 = 1700 * 930 * 0.002 * 40 = 126480 J.

2) Change in copper temperature: Δt1 = Q / (C1 * m1) = 126480 / (370 * 0.51) = 670.27 ºС.
