3 cards from this section. Quick, good the night before a test.
What does calorimetry measure?
Think about what happens when hot and cold substances come together.
What is a calorimeter made of?
Consider materials that conduct heat well.
What is the primary focus of calorimetry?
Think about what involves heat exchange.
True or False: In calorimetry, heat lost by one body is always greater than heat gained by another.
Remember the law of conservation of energy.
Calculate the specific heat capacity of an unknown metal, given that a 0.15 kg piece of metal at 120 °C is dropped into a calorimeter containing 0.5 kg of water at 20 °C, and the final temperature is 30 °C.
Think about how to express the heat exchange using Q = mcΔT.
You are heating 1 kg of ice at 0 °C to steam at 100 °C. Calculate the total heat required, given the latent heats of fusion and vaporization.
Remember to account for all phases of temperature change.
