A calorimetry lab measures heat transferred during a physical or chemical process by observing temperature changes. For example, you might place a heated metal sample in water and use the water’s temperature rise to estimate the metal’s specific heat. The key is to track where the heat goes and make your assumptions clear.
What is chemistry lab work?
Chemistry lab work involves observing substances, making measurements and using evidence to answer questions. In calorimetry, the question is often how much heat a process releases or absorbs.
In a specific heat experiment, a warm sample is placed in cooler water. Energy moves from the sample to the water until they reach a shared final temperature. If heat exchange with the cup and surroundings is negligible, the heat gained by the water is approximately equal to the heat lost by the sample: q_water ≈ −q_sample.
A process can also change the temperature of a solution. For example, dissolving a substance can warm or cool water; the solution’s temperature change helps estimate the heat associated with dissolving.
What is chemistry lab equipment?
A coffee cup calorimeter is typically an insulated cup with a lid and a temperature probe or thermometer. It limits heat exchange with the surroundings but does not eliminate it. The setup is commonly used to study processes at approximately constant pressure.
You may also use a balance to measure mass, a graduated cylinder to measure liquid volume, and a stirring device to help the mixture reach a uniform temperature. Record the precision of each measurement. The chemistry lab equipment guide explains more common tools and their uses.
Follow your lab’s safety directions, wear the required protective equipment, and let an instructor or lab manual guide any heating and chemical handling.

How do you work in a chemistry lab?
A typical specific heat procedure compares a heated sample with cooler water. Follow the assigned procedure rather than substituting materials or temperatures.
- Measure the mass of the sample and the mass of water in the calorimeter.
- Record the initial temperature of the water and the sample.
- Place the sample in the water, cover the calorimeter and gently stir as directed.
- Record the final equilibrium temperature and calculate ΔT = T_final − T_initial for each material.
- Calculate heat gained by the water and use it to estimate the sample’s specific heat.
For example, suppose 100.0 g of water warms from 20.0°C to 25.0°C. Using water’s specific heat of 4.184 J/(g·°C), q_water = (100.0 g)(4.184 J/(g·°C))(5.0°C) = 2,092 J. The water gained heat, so its q is positive.
If a 50.0 g sample cools from 125.0°C to 25.0°C, its ΔT is −100.0°C. Assuming the water gains all the heat the sample loses, q_sample ≈ −2,092 J. Rearranging q = mcΔT gives c_sample ≈ (−2,092 J)/[(50.0 g)(−100.0°C)] = 0.4184 J/(g·°C). Actual results may differ because the cup and surroundings also exchange heat. For more on recording measurements, see measurement in chemistry.

See the Chemistry Lab course →How do you write a chemistry lab report?
A calorimetry report should show what you measured, how you calculated heat and what limits your conclusion. Use the format and rubric assigned by your instructor.
- State the experiment’s purpose and briefly describe the procedure.
- Present masses and initial and final temperatures with units.
- Show ΔT and q calculations, including signs and the assumed specific heat of water.
- Report the result with appropriate units and precision.
- Discuss uncertainty, such as heat absorbed by the cup, heat lost to air or a sample cooling during transfer.
Explain how a source of error might affect the result rather than simply listing it. The guide to writing a chemistry lab report offers a fuller outline.
