Question

How much heat does it take to melt an ice cube (m= 8g) which had a temperature of -10ºC (ΔT=10 K)?

Answer #1

Let it takes heat to melt the ice.

We know the specific heat for ice is C=2093 J/Kg. K.

The latent heat of ice is L=334
10^{3} J/kg.

The temperature difference
=10^{o}C.

The mass of the ice m=8 g=0.008 kg.

It will take 2839.44 J heat to melt 8 g of ice.
