Calculate the heat transfer (J) when 3.15 g of platinum (specific heat capacity = 0.133 J g^-1 °C^-1) at 86.1 °C cools to room temperature, 24.3 °C.

Question

Quizplus · Accepted Answer

The heat transfer can be calculated using the formula q = mcΔT. Here, m = 3.15 g, c = 0.133 J/g°C, and ΔT = (24.3 - 86.1) °C = -61.8 °C. Thus, q = 3.15 g * 0.133 J/g°C * (-61.8 °C) = -25.9 J, which rounds to -26 J.
