Assertion : If water is filled in a balloon and this is immersed in water itself. Then volume of water displaced is equal to the volume of water filled in the balloon. Reason : Volume of a liquid displaced is equal to the volume of solid immersed in that liquid. Assertion : When an ideal [...]

Assertion : A solid object of iron is dipped in water, both are at same temperature of 2∘C. If the temperature of water is increased by 2∘C, then the buoyancy force action of the object will increase. Reason : If we increase the temperature of water from 2∘C to 4∘C, then density of water will [...]
