Question

A 1kg block of ice at 0o C falls into alake whose

Answer 1

Answer:

340.01019 m

Explanation:

m =  Mass of ice = 1 kg

$L_f$ = Latent heat of fusion = $333.55\times 10^3\ J/kg$

g = Acceleration due to gravity = 9.81 m/s²

M = Mass of water = 0.01 kg

The potential energy will balance the heat released

$mgh=ML_f\\\Rightarrow h=\dfrac{ML_f}{mg}\\\Rightarrow h=\dfrac{0.01\times 333.55\times 10^3}{1\times 9.81}\\\Rightarrow h=340.01019\ m$

The minimum altitude is 340.01019 m
