Frequently Asked Questions

What is calorimetry?

Calorimetry is the science of measuring heat changes in chemical or physical processes. A calorimeter isolates a reaction to measure temperature change, which is then converted to heat using q = mcΔT or q = CΔT.

What is the difference between a coffee cup and bomb calorimeter?

A coffee cup calorimeter operates at constant pressure (measures ΔH), uses a simple insulated container with water, and is suitable for solution reactions. A bomb calorimeter operates at constant volume (measures ΔE), uses a sealed steel vessel, and is used for combustion reactions.
