How many calories are needed to change 1 gram of 100 degrees Celsius boiling water to 100 degrees Celsius steam?

This is the latent heat of vaporisation of water, which at standard pressure, is 539 calories (per gram).


How many btus are required to change five pounds of ice at 20 degrees to steam at 220 degrees?

6,520 Btus


Is the temp of steam at 100 degrees celsius same as 100 degrees celsius water?

Leaving aside the effects of pressure, yes, the temperatures are the same. But the amount of heat (thermal energy) per gram, is much greater for the steam.


How much heat is needed to change 3.0kg of ice at -10 degree into steam at 300 degree Celsius?

All calculations below are assumed done with all materials (ice, water, and steam) being at normal atmospheric pressure. 3.0kg is 3000 gm. Heat required to raise temperature of ice from -10 degree celcius to 0 degrees celcius is 3000 x 10 cals. (A) The latent heat of fusion of ice is 80 cals per gm. So heat needed to melt 3000 gm of ice at 0 degrees celcius is 3000 x 80 cal. (B) The heat required to convert 3000 gms of water from 0 degrees celcius to 100 degrees celcius is 3000 x 100 cals. (C) The latent heat of vaporization of steam is approximately 540 cals per gm. Hence heat required to convert 3000 gms of water to steam at 100 degrees celcius is 3000 x 540 cals. (D) Now add (A) + (B) + (C) + (D) = 30000 + 240000 + 300000 + 1620000 cals. And that is = 2190000 cals = 2.19 X 10 to power 6 cals.


How much heat is required to convert 1.00 kg of water at 100 degrees Celsius to steam at 100 degrees Celsius?

What must happen for gaseous water to become liquid water?

It has to give up quite a lot of heat. A pound of steam carries 940 btu's of heat that has to be transferred out to end up with one pound of water at the same temperature. It only takes 180 btu's to raise water from 32 degrees Fahrenheit to 212 degrees.
