Answer:
83.5kJ
Explanation:
To answer to this question, you need the equation:
Q=ice×m
Q
is the amount of heat needed to melt the ice,
L
ice
is the Latent Heat of melting for ice, and
m
is the given mass of ice. Various tables of latent heats give us:
ice=3.34⋅105Jkg
m=250g=0.25kg .
So:
Q=(3.34⋅105Jkg)×(0.25 kg)=83,500J=83.5kJ
