1. Complete sentences using the words in the box.
- Exothermic reactions transfer heat from the reacting chemicals into the surroundings.
- We can measure the energy transferred by measuring the temperature increase in the reaction.
- During endothermic reactions there is a decrease in temperature.
- This is because energy is transferred from the surroundings into the reacting chemicals.
2. Look at the reactions below. Label each reaction as endothermic or exothermic in the space provided below.
- Respiration: Exothermic
- Neutralisation: Exothermic
- Photosynthesis: Endothermic
- Thermal decomposition: Endothermic
- Burning fuels: Exothermic
Parent Tip: Review the logic above to help your child master the concept of exothermic and endothermic reactions worksheet answers.
