I meant making mistakes - that's a part of education.

See, he's getting me.

Q-100g ice at 0?C is mixed with 10g steam at 100?C. Find the final temperature and composition.
How to solve?

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.

You're still gonna miss...

Hence I'm gonna fire a mega nuke, so that I don't miss

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.

I've anti-submarine measures in place...

What about sharks, are you going to eat them too, just because its still a fish?

Er, in the answer it is given that the resulting temperature is 0?C, and the ice and water remaining in the mixture is 20g and 90g respectively....i didn't understand how?

It'll never happen, needs launch codes, see.

& when you're drunk , you won't remember the codes. I think this is the best time to take you to a zoo.

re: WC 100K Post Challenge - You Ready?!

Are the mixtures at S.T.P??

Err, nothing mentioned in the question about this, but I think we can assume it is STP by default.

Antarctica is a "polar" region, there is no precipitation, it has no lakes or rivers and is in fact the driest continent. Average temperatures in the Antarctic interior get down to -70 degrees Celsius during the winter months and -35 degrees Celsius in the warmer months. The coastal temperatures are much warmer with a range of -15 to -32 Celsius in Winter and -5 to +5 Celsius in Summer. The interior of Antarctica is considered the world's driest desert because the extreme cold freezes water vapour out of the air. Annual snowfall on the polar plateau is equivalent to less than 5 cm of rain. Antarctica has some of the strongest winds on earth, with some winds reaching 320 kph.

So, no snowflakes, see.

& you get this information from your friends in Antarctica?

Not for the penguin full of rum *hic*

The drunk penguin has waken up and going to blow the whole forums up a again?

re: WC 100K Post Challenge - You Ready?!

Deserts are hot, Artartica is.... Not so hot!

Well, a region is called a desert or not, is based on the rain amount, not the temperature, so, Antarctica is a desert.

Our talking penguin us living in a desert, see?

The lack of education in here is shocking, see. No wonder they've got high post counts...

*lays down, plots*

What's that generalization? Feel... offended -_-

Oh wait, I don't have big post count, then... I'm an exception, eh?
