Practice Test 9

A student heats a 100.0 g sample of liquid water in a beaker. The temperature of the water increases from 22.0°C to 28.0°C. Assume the specific heat capacity of water is $4.18\ \text{J},\text{g}^{-1},^{\circ}\text{C}^{-1}$. What is the heat transferred to the water, $q$?

A student adds heat to a 120 g sample of aluminum, causing its temperature to increase from 20.0°C to 45.0°C. The specific heat capacity of aluminum is $0.90\ \text{J},\text{g}^{-1},^{\circ}\text{C}^{-1}$. What is the heat absorbed by the aluminum sample?
