q = mHv
q = heat
m = mass (30g)
Hv = heat of vaporization (2,260J/g)
q = (30g)(2,260J/g)
q = 67,800J
When 30 grams of water is converted into steam, how much heat is absorbed?
67,800J of heat, also represented as 67.8kJ of heat is absorbed.
To raise the temperature of 1 pound of water 1 degree F requires one BTU. If one pound of water at 62 degreesF is raised to 212 degreesF liquid, 150 BTU's would be required. When one pound of water at 212 degreesF is converted to steam, an additional 970 BTU's are absorbed. The total number of BTU's absorbed in converting one pound of water at 62degreesF to steam is 1,120 BTU's. Water weighs 8.33 pounds per gallon One gallon of water, when converted to steam, will absorb 9,330 BTU's (8.33 times 1,120)
If all the water boils off, the mass of the steam will be 100 grams. Matter cannot be created or destroyed.
The liquid mass is partly converted to a gas (steam, water vapor), so if this escapes, the mass is no longer there. The steam can, however, be captured and condensed, and used again (as in steam engines).
What is the total number of Joules of heat absorbed by 65.00 grams of water when the temperature of th water is raised from 25.00 C to 40.00 C
It really depends on the temperature of the steam and temperature of the cold surface. 250 degree steam hitting a 50 or 60 degree surface will just turn back into water and droplets can be seen almost immediately. 1000+ degree steam hitting a frozen surface may cause a loud bang and eventually turn back into water.

60ml of water is 60 grams.
Thermal energy, when absorbed by water
1,732 grams of water is 1,732 ml
At 212 degrees Fahrenheit water expands approximately 1,700 its original volume when converted to steam.
Some of the sun's energy is converted into wind and water waves. Most of the sun's energy are absorbed by the primary producers.
Steam
It is absorbed into the drier air from outside the bathroom.
yes, water is heated by earth's interior and converted to steam
If all the water boils off, the mass of the steam will be 100 grams. Matter cannot be created or destroyed.
The gas being evaporated forms the bubbles in boiling water.
atmosphere, land and water Also Thermal Energy!
