Calorimetry

What is the primary purpose of calorimetry?

• Measuring temperature changes in a system

• Measuring the amount of light absorbed by a substance

• Measuring the quantity of heat transferred during a process

• Measuring the volume of a chemical reaction

Which of the following are essential components of a calorimeter designed to measure energy changes in a chemical system?

• A chemical system, a heat bath, and a thermometer

• A beaker, a Bunsen burner, and a stopwatch

• A test tube, a stirring rod, and a balance
