Q13. (a) When does a body sinks in a fluid? (b)Why does a balloon filled with hydrogen gas rise up against gravity?

Q14. (a) Which has greater density: 1 kg of iron or 2 kg of iron? (b)If a hollow sphere and a solid sphere are both made of the same amount of iron, which sphere has greater average density?

Q15. A. A body weighs 10 N in air and 8 N when fully immersed in water. How much is the buoyant force acting on the body? B. Why are the buoys making the channel in a river are hollow spheres?

Q16. State one important effect produced by the buoyant force exerted by water.

Q17. Where does a solid weigh more- in air or in a liquid?

Q18. Name two factors on which the buoyant force depends?

Q19. What is the relationship between the buoyant force on an object and the liquid displaced by it?

Q21. The density of turpentine oil is 840 kg/m3. What will be its relative density?

Q22. Explain why big boulders can be moved easily by floods.

Q23. Why is a slight blow on a cork of bottle fully filled with a liquid sufficient to break the bottle?

Q24. Why is it easier to walk on soft sand with a flat shoe than a pencil-heeled shoe?

Q25. Lead has greater density than iron and both are denser than water. Is the buoyant force on a lead pencil greater than, less than or equal to the buoyant force on an iron object of same volume?

Q26. Why do you feel lighter when you swim?

Q27. Why is a bucket of water lighter when in water than when it is taken out of water?

Q28. Why it is easier to swim in sea water tan in river water?
