Question

Petrol density=800kg\m3 Water density = 1000kg/m3 Q)a) which has more mass 1 m3 of petrol or 1 m3 of petrol

b)which has more volume 1 kg of petrol or 1 kg of water

Q)2) how to claculate volume with density and mass?

Answer 1

1. Petrol density = 800 kg/m³. Water density = 1000 kg/m³. Q a) Which has more mass 1 m³ of petrol or 1 m³ of petrol? b) Which has more volume 1 kg of petrol or 1 kg of water? Q) 2) how to calculate volume with density and mass?

$$V _ {2} = \frac {m}{\rho_ {2}} \text{ (here, } m = 1 \mathrm{kg}).$$

As ρ₁ < ρ₂, than V₁ > V₂. So, 1 kg of petrol has more volume than 1 kg of water.

Q2) Volume can be found as V = m/ρ.

Answer: Qa) water; Qb) petrol; Q2) V = m/ρ.
