The latent heat of condensation of steam is 2260 Joules per gram (539.3 cals/g). So the amount of heat released by 12.4 g = 12.4*2260 Joules = 28,024 Joules or 6687 cals.

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 required to convert 1.00 kg of water at 100 degrees Celsius to steam at 100 degrees Celsius?

Assuming standard atmospheric pressure, 2260 kilojoules.


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 much heat energy will be required to lower the temperature of 2.67kg of steam from 282 degrees Celsius to 105 degrees Celsius?

You mean how much heat energy will be lost/transferred as you are losing Joules here. All in steam, so a simple q problem and no change of state. 2.67 kg = 2670 grams q = (2670 grams steam)(2.0 J/gC)(105 C - 282 C) = - 9.45 X 105 Joules ----------------------------------- This much heat energy must be lost to lower the temperature of the steam.


How much heat is necessary to change a 52.0 gram sample of water at 33.0 degrees Celsius into steam at 110 degrees celsius?

Raise the temp of 52 grams of water from 33.0 C to 100 C = 52*67*4.184 = 14.577 kJConvert evaporate 52 g of water to steam without change of temp = 52*2259 = 117.468 kJRaise the temp of 52 grams of steam from 100 C to 110 C = 52*10*2.02 = 1.051 kJTotal energy required = 133.095 kJ = 31,811 calories or 31.811 kCal.

How much heat is released when 1000g of steam at 100 degrees Celsius condenses?

When steam at 100 degrees Celsius condenses, it releases 2260 Joules of energy per gram. Therefore, for 1000g of steam, the heat released would be 2,260,000 Joules (2260 J/g * 1000 g).


Why is steam at 100degree celsius more dangerous than water at 100degree celsius?

Steam at 100 degrees Celsius is more dangerous than water at 100 degrees Celsius because steam carries more heat energy and can cause deeper burns on contact with skin. Additionally, steam has a greater ability to penetrate clothing and protective gear, increasing the risk of burns.


What is the steam point of the Celsius scale?

at 100 degrees liquid water will go to steam and steam will go to liquid water


What temperature does steam condense?

When water reaches boiling, it becomes steam. Once the water cools down, typically below 100 degrees Fahrenheit, it will begin to form water droplets or condensation.


What gas first appears as a colourless gas then when cooled it condenses into a colourless liquid and boils at 100 degrees celccius?

The most probable answer for your your question is pure water.


How much heat is released when 160 grams of steam at 100 degrees C liquefies?

The heat released when steam at 100 degrees Celsius condenses into liquid water is equal to the heat it absorbed during the phase change from liquid water to steam. This heat is known as the latent heat of vaporization, which for water is approximately 2260 J/g. Therefore, the amount of heat released when 160 grams of steam liquefies is approximately 160g x 2260 J/g = 361,600 J.


What happens to steam at 105 degrees Celsius?

At 105 degrees Celsius, steam will remain in the gaseous phase as it is above the boiling point of water (100 degrees Celsius). Steam will continue to condense into liquid water only once it cools down below the boiling point.


Water becomes steam at what degrees?

Water becomes steam at 100 degrees Celsius under normal atmospheric pressure.


What happens if you heat the steam above 100 degrees celsius?

If you heat steam above 100 degrees Celsius, it will continue to increase in temperature without changing to water. This is because steam is already in a gaseous state at temperatures above 100 degrees Celsius.


What temperature does water turns into steam is degrees Celsius?

It can be anywhere in between 60C and 100C (boiling point).


Can steam be formed at 120 degrees Celsius?

Yes, it can.


How many calories are needed to convert 12.5 grams of ice at 0 degrees Celsius to steam at 100 degrees Celsius?

To convert 12.5 grams of ice at 0 degrees Celsius to steam at 100 degrees Celsius, you would need to provide heat energy for three main processes: heating the ice from 0 degrees Celsius to 100 degrees Celsius, melting the ice into water at 0 degrees Celsius, and then heating the water from 0 degrees Celsius to steam at 100 degrees Celsius. The total calorie requirement would be determined by the specific heat capacities and heat of fusion and vaporization of water.
