# Enthalpy Changes and Calorimetry Word Search

In Chemistry 30, you determine and interpret energy changes in chemical reactions ([Topic](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23633)). A core skill is using calorimetry data to find enthalpy changes ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23641)), which requires understanding how heat transfer relates to temperature change through the equation Q = mcΔt ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/23634)). You learn to define enthalpy and use ΔH notation to communicate energy changes ([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/23638)). This word search reinforces the vocabulary of thermochemical analysis: the equipment you use, the processes you measure, and the precision required for accurate results.

## How to play

- Find and circle each word in the grid. Words may run horizontally, vertically, or diagonally in any direction (left to right, right to left, top to bottom, bottom to top).
- All eight words are hidden in the puzzle. Use the word list below to check off words as you find them.
- Mark your answers on the grid itself, or record them on a separate sheet with the row and column coordinates where each word begins.

## Words to find

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