univerkov | April 28, 2021 | education

Problem data: m (mass of mercury to be heated) = 2 kg; Δt (change in temperature of mercury) = 1 ºС.

Reference values: Cp (specific heat capacity of mercury) = 140 J / (kg * K).

The required amount of heat for heating 2 kg of mercury is calculated by the formula: Q = Ср * m * Δt.

Let’s calculate: Q = 140 * 2 * 1 = 280 J.

Answer: To heat 2 kg of mercury, 280 J of heat is needed.
