Answer:
1. True - it can be done by applying lubricant
2. True - when there are irregularities only then friction exists
3. False - Friction acts opposite to the relative motion of the body
4. False - Magnitude of friction is directly proportional to the magnitude of friction
5. True - Talcum Powder gets filled between the irregularities leaving no space for interlocking
6. True - Friction is directly proportional to the irregularities of the surface
7. True - It acts opposite to the relative motion
8. True - Denser liquids undergo more friction.
