To

Quizplus · Accepted Answer

Using the equation Q = m*c*∆T, where Q is the heat absorbed/released, m is the mass of the substance, c is the specific heat capacity of the substance, and ∆T is the change in temperature, we can calculate the heat absorbed by 948.0 g of water:

Q = m*c*∆T = 948.0 g * 4.184 J/g°C * (21.8°C - 11.0°C)
Q = 29,706.14 J = 29.70 kJ

Therefore, the heat absorbed by the water is 29.7 kJ (choice D).
