Question

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

water is also at 0o C, and 0.01 kg of the icemelts. What
was the minimum altitude from which the icefell?

Answer 1

340.01019 m

Step-by-step explanation:

m = Mass of ice = 1 kg

`L_f` = Latent heat of fusion =
`333.55* 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=(ML_f)/(mg)\\\Rightarrow h=(0.01* 333.55* 10^3)/(1* 9.81)\\\Rightarrow h=340.01019\ m`

The minimum altitude is 340.01019 m
