Reaction of Metals with water
Lesson 4

Slide 5 - Slide

Recall of the previous lesson
  • Exothermic reaction:
- heat is released to the outside to make chemical bonds and form NEW products
- the product becomes warmer 
- there is an increase in temperature

Slide 6 - Slide

Recall of the previous lesson
  • Endothermic reaction:
- heat is absorbed from the outside to break the chemical bonds to form NEW products
- the product becomes cooler 
- there is a decrease in temperature
