Best answer

(a) 1 kg is the mass of 1000 ml of water at 4°C.

(b) Mass = density x volume.

(c) The S.I. unit of density is Kg m^-3

(d) Density of water is 1000 Kg m^-3

(e) 1 g cm^-3 = 1000 Kg m^-3.

(f) The density of a body which sinks in water is more than 1000 Kg m^-3

(g) A body sinks in a liquid A, but floats in a liquid B. The density of liquid A is less than the density of liquid B.

(h) A body X sinks in water, but a body Y floats on water. The density of the body X is more than the density of body Y.

(i) The buoyant force experienced by a body when floating in salt water is equal to or same that of when floating in pure water.

(j) The weight of a body floating in a liquid is zero.
