# Enthalpy Changes and Calorimetry Word Search

This puzzle reinforces vocabulary from Unit A: Thermochemical Changes, where students define enthalpy for chemical reactions ([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 apply Q = mcΔt to heat transfer problems ([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)). A calorimeter built from a polystyrene cup allows students to test experimental precision while collecting temperature and mass data ([Resource](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/resource/0uxhxD914kqzmssVwCK4tg)), and a combustion lab demonstrates how an exothermic reaction transfers thermal energy to water during calorimetry ([Resource](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/resource/9ykNTynh306g6EnZlkTITQ)). Locate each term below to review the language you will need for lab reports and diploma exam questions on this unit.

## How to play

- Scan the grid horizontally, vertically, and diagonally, in both forward and reverse directions, to locate each term from the word list.
- Circle or highlight each word as you find it, then cross it off the list to track your progress.
- Work through the full list before checking the answer key, since several terms share overlapping letters and can be mistaken for one another.

## Words to find

- CALORIMETER
- CALORIMETRY
- COMBUSTION
- ENTHALPY
- EXOTHERMIC
- POLYSTYRENE
- PRECISION
- TEMPERATURE
