Key Stage 3
Meaning
An exothermic process is one that gives out energy. This usually causes surroundings to increase in temperature.
About Exothermic Processes
- Most chemical reactions are exothermic with means they release energy to the environment and this is observed by an increase in temperature.
- Freezing, Condensing and Depositing are exothermic changes because it releases energy when it happens. The material has less after it has happened. However, there is usually no increase in temperature because the material is being cooled to change state.
