We will find the total heat that must be added to $0\mathrm{.}8$ kg of water at $-30C$ in order to raise it to $114C.$

First find the heat required to bring the ice to its melting point temperature $(0C).$

$Q_1=$

kcal

Next find the heat required to melt the ice $($while remaining at $0C).$

$Q_2=,{\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}$kcal

Find the heat required to bring the melted water up to its boiling point temperature $(100C).$

$Q_3=$

kcal

Find the heat required to vaporize $($boil$)$ the hot water $($while remaining at $100C).$

$Q_4=$

kcal

Finally, find the heat required to bring the water vapor up to its final temperature $(114C)$ while held at constant volume. Use $c=0\mathrm{.}363$kca$\frac{l}{kgC}.$

$Q_5=$

kcal

What is the total heat that must be added to $0\mathrm{.}8$ kg of water at $-30C$ in order to raise it to $114C.$
