$=2257\frac{J}{g}.$

For a sample of water at $1\mathrm{.}0$atm of pressure, mass $=177g$ at an initial temperature of $-39C$ and a final temperature of $340C,$ answer the following questions:

$(1)$ how much heat is required to warm the solid sample to its melting point? J

$(2)$ how much heat is required to melt the sample?

j

how much heat is required to warm the liquid sample to its boiling point?

how much heat is required to vaporize the sample?

J

$(5)$ 'how much heat is required to warm the gaseous sample to its final temperature?

and finally, $(6)$ how much heat is required for the entire process to occur?
