Question

Density of ice is rho and that of water is sigma. What will be the density in volume when a mass M of ice melts?

Answer 1

Answer:

Explanation:

Mσ−ρ

(sigma-rho)/(M)`

M[1ρ−1σ]

1M[1ρ−1σ]

Answer :

C

Solution :

Volume of ice = Mρ volume of water = Mσ

Answer 2

Answer:

Explanation:

Volume of ice Vi = Mass/Density = M/ρ Volume of ice Vw = Mass/Density = M/σ Decrease in volume = Vi − Vw = M/ρ − M/σ = M(1/ρ − 1/σ). Therefore, the decrease in volume when a mass of ice melts is M(1/ρ − 1/σ).
