A sample of copper absorbs 43.6 kJ of heat,resulting in a temperature rise of 75.0°C,determine the mass (in kg)of the copper sample if the specific heat capacity of copper is 0.385 J/g°C.

Question

Quizplus · Accepted Answer

The correct answer is A because:The mass of the copper sample can be calculated using the formula:mass = heat absorbed / (specific heat capacity * temperature change)mass = 43.6 kJ / (0.385 J/g°C * 75.0°C) = 1.51 kg
