# Enthalpy and Calorimetry Word Search

This puzzle reviews the vocabulary Chemistry 30 students need for Unit A: Thermochemical Changes. Students determine and interpret energy changes in chemical reactions ([Topic](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23633)), define enthalpy for a reaction ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23636), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23636)), and use ΔH notation to communicate energy changes ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23638)). Calorimetry experiments generate the temperature and mass data used to calculate molar enthalpy change ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23647), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23648)), applying Q = mcΔt to analyze heat transfer ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23634), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23634)) and using that calorimetry data to determine enthalpy changes for exothermic and endothermic reactions ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23641)). Building and testing a calorimeter for precision, and measuring the heat released during combustion, are lab skills tied directly to this unit ([Resource](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/resource/9ykNTynh306g6EnZlkTITQ), [Resource](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/resource/0uxhxD914kqzmssVwCK4tg)).
