Calculate the amount of heat absorbed by a 40.0 g sample of water at 21 °C when the temperature is raised to 35 °C.

Question

Quizplus · Accepted Answer

The heat absorbed by the water can be calculated using the formula q = mcΔT, where m is the mass (40.0 g), c is the specific heat capacity of water (4.18 J/g°C), and ΔT is the change in temperature (35°C - 21°C = 14°C). Calculating gives q = 40.0 g * 4.18 J/g°C * 14°C = 2345.6 J = 2.3 kJ.
