how-much-energy-will-it-take-to-melt-100-grams-of-ice-at-0-c

The answer is: ##33.4kJ##

To answer to this question it is sufficient to use this equation:

##Q=Lm##

where

##Q## is the amount of heat needed to melt the ice (the request of the problem;

##L## or ##L_(ice)## is the of melt for ice, that is:

##L_(ice)=3.34 · 10^5 J/(kg)##;

##m## is the mass of ice that is to melt, that is:

##m=100g=0.1kg##.

So:

##Q=3.34 · 10^5 J/(kg).0,1kg=33,400J=33.4kJ##
