You're wrong.

Geography (from Greek γεωγραφία, geographia, lit. "earth description") is a field of science dedicated to the study of the lands, the features, the inhabitants, and the phenomena of the Earth.
A literal translation would be "to describe or write about the Earth".

Oh shoot penguin knows what's up o_O best not to trifle with you :p

Now I'm sad. Really sad. Since when did geography not fall under science? When did that happen? Was there a vote and I wasn't invited or something?

Since it's not emphasized as science anymore . I remember back in middle school and high school we didn't have to take geography it was more of an elective . They would rather have you take biology and or Chem over geography

Use the following equation to determine the amount of energy required to melt the ice.
Q = mass * Hf = 3.36 * 10^5 J

Use the following equation to determine the amount of energy required to increase the temperature of water from 0 to 100.

Q = mass * Specific heat * ∆T
Specific heat = 4186 J/(kg * ˚C)
Q = 1 * 4186 * 100 = 418,600 J
Total energy required = 3.36 * 10^5 + 418,600 = 7.546 * 10^5 J

This is the amount of energy that is required to melt the ice and increase the temperature of the water to 100˚C. Let?s use this number in the following equation to determine the amount of steam that it will condense.

Q = mass * H vap = 2.26 * 10^6 J
7.546 * 10^5 = mass * 2.26 * 10^6
Mass = 7.546 * 10^5 ? 2.26 * 10^6 = 0.333893805 kg

This is approximately 0.334 kg. This means all of the steam didn't condense. To determine the mass of steam that didn't condense, subtract this number from 1kg. The mass is approximately 0.666 kg.

Wtf ._. Oh gosh that made my head hurt. Heck I can't do C? because it's too confusing x.x

Nothing wrong with making mistake. What you said wasn't a mistake, it was wrong. A simple search on the net would have told you differently so you weren't only wrong but lazy.

Heard that one before :p Mia said it to me many times :p
