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 increase. Ignore expansion of solid sphere.
