Compare the volumes of 1 kilogram of water, mercury and milk. Which substance has a larger volume and how many times?

mw = 1 kg.

mrt = 1 kg.

mm = 1 kg.

ρw = 1000 kg / m ^ 3.

ρрт = 13600 kg / m ^ 3.

ρm = 1030 kg / m ^ 3.

Vv / Vrt -?

Vw / Vm -?

The density of a substance ρ is determined by the formula: ρ = m / V, where m is the mass of the substance, V is the volume of the substance.

V = m / ρ.

Since the mass of matter m is the same for all, and the density ρ is in the denominator, the volume V will be large for the substance with the lowest density ρ.

The smallest volume will be for 1 kg of water.

Vв / Vрт = mв / ρв: mрт / ρрт = ρрт / ρв.

Vw / Vrt = 13600 kg / m ^ 3/1000 kg / m ^ 3 = 13.6.

Vw / Vm = mw / ρw: mm / ρmt = ρm / ρw.

Vw / Vrt = 1030 kg / m ^ 3/1000 kg / m ^ 3 = 1.03.
