# A student places a sample of hot water with a mass of \(50.0 \text{ g}\) at \(70.0^\circ\text{C}\) into a calorimeter. The water cools to room temperature, \(20.0^\circ\text{C}\). Assuming the specific heat capacity of water is \(4.2 \text{ J/(g}\cdot^\circ\text{C)}\), what is the magnitude of the thermal energy transferred from the water as it cools?

A student places a sample of hot water with a mass of \(50.0 \text{ g}\) at \(70.0^\circ\text{C}\) into a calorimeter. The water cools to room temperature, \(20.0^\circ\text{C}\). Assuming the specific heat capacity of water is \(4.2 \text{ J/(g}\cdot^\circ\text{C)}\), what is the magnitude of the thermal energy transferred from the water as it cools?

- **A.** \(10.5 \text{ kJ}\)
- **B.** \(14.7 \text{ kJ}\)
- **C.** \(16.8 \text{ kJ}\)
- **D.** \(18.9 \text{ kJ}\)
