Q-100g ice at 0?C is mixed with 10g steam at 100?C. Find the final temperature and composition.
How to solve?
You're still gonna miss...
Hence I'm gonna fire a mega nuke, so that I don't miss

Ever play battleship?
I've anti-submarine measures in place...
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.
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.
It'll never happen, needs launch codes, see.
Are the mixtures at S.T.P??
New wot?
& when you're drunk , you won't remember the codes. I think this is the best time to take you to a zoo.
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.
Not for the penguin full of rum *hic*
Deserts are hot, Artartica is.... Not so hot!

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