- Friction causes the temperature of an object to increase
- Friction occurs when two object 's surfaces move against each other
- Hence, when friction occurs between two objects, both objects' temperatures increase

- A wooden block is pushed across a sheet of sandpaper
- An object being pushed across another object causes their surfaces to move against each other
- So, the surfaces of a wooden block and sandpaper are moving against each other

- The surfaces of a wooden block and sandpaper are moving against each other
- Friction occurs when two object 's surfaces move against each other
- Hence, friction occurs when the wooden block is moving against the sandpaper

- When friction occurs between two objects, both objects' temperatures increase
- Friction occurs when the wooden block is moving against the sandpaper
- So, friction will cause the temperature of the wooden block to increase

Therefore, friction will cause the temperature of the wooden block to increase
