Define the term specific latent heat of vaporization.

Identify the part representing latent heat of fusion in the temperature vs heat graph for melting of ice.

Write the quadrants in which the following points lie:

$\left(-4,7\right)$

Define Specific latent heat of fusion.

How much ice at $-10°\mathrm{C}$ must be dropped into a cup containing $300 \mathrm{g}$ of water at $20°\mathrm{C}$ in order for the temperature of the water to be reduced to $10°\mathrm{C}$? The cup itself has a mass of $150 \mathrm{g}$ and is made out of aluminium. Assume that no energy is lost to the surroundings.

$($Specific heat capacity of ice$=2200 \mathrm{J} {\mathrm{kg}}^{-1} {\mathrm{K}}^{-1};$ specific latent heat of fusion of ice$=334 \mathrm{J} {\mathrm{kg}}^{-1} {\mathrm{K}}^{-1};$ specific heat capacity of water$=4200 \mathrm{J} {\mathrm{kg}}^{-1} {\mathrm{K}}^{-1}.)$
