- Heat means temperature increases
- A solid is heated
- So, the temperature of the solid increases

- The temperature of the solid increases
- A solid is a kind of substance
- Hence, the temperature of the solid substance increases

- The temperature of the solid substance increases
- As the temperature of a substance increases , the molecules in that substance will move faster
- Therefore, the molecules in the solid substance moves faster

- The molecules in the solid substance moves faster
- Faster means an increase / higher in speed
- Hence, the molecules in the solid substance increases in speed

Therefore, the molecules in the solid substance increases in speed
[Question]Which of the following changes occurs as a solid is heated?
[Context]- A solid is a kind of substance 
- Faster means an increase / higher in speed 
- As the temperature of a substance increases , the molecules in that substance will move faster 
- Heat means temperature increases 
- A solid is heated
