# Enthalpy Changes and Calorimetry Word Search

In Chemistry 30, you investigate energy transfer in chemical reactions through calorimetry experiments ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23641)). Understanding how to use calorimetry data to determine enthalpy changes requires familiarity with key terms and concepts: the calorimeter itself, the principles of calorimetry, the heat equation Q = mcΔt ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23634)), exothermic and endothermic processes, the notation used to express enthalpy change ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23638)), and the materials and precision required for accurate measurements ([Resource](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/resource/0uxhxD914kqzmssVwCK4tg)). This word search reinforces the vocabulary you need to master thermochemical analysis.
