Answer: again these are equations you should know; I hope you WILL LEARN them, and how to write your own; these must have come from the book or lecture, and I do not want to berate you, I want you to improve more every day. But it is very late here, and I must finally go. Study hard!

No matter what, study hard.

I loved research; tons of fun, meeting new people, and learning new things.

Hopefully many people here will also.

I bid you all a Good Night.

How much energy is lost to condense 300. grams of steam at 100.C?
True [87]

Energy lost to condense = 803.4 kJ

<h3>Further explanation</h3>

Condensation of steam through 2 stages:

1. phase change(steam to water)

2. cool down(100 to 0 C)

1. phase change(condensation)

Lv==latent heat of vaporization for water=2260 J/g

\tt Q=300\times 2260=678000~J

2. cool down

c=specific heat for water=4.18 J/g C

\tt Q=300\times 4.18\times (100-0)=125400

Total heat =

\tt 678000+125400=803400~J
