For this problem, use a specific heat of water of $4186$ J$/($kg$-$C$\backslash$deg $)$ and a latent heat of vaporization of $2\mathrm{.}26\backslash$times $10^6$ J$/$kg$.$

Part $1$:

What is the minimum length of time necessary to bring to a boil $1\mathrm{.}30$ L of water, initially at $21\mathrm{.}0\backslash$deg C$,$ using as a source of heat the $1850$ W heating element on a stove?

Part $2$:

What additional minimum time is necessary to boil the water away?
