What is the name of heat energy that changes ice into water and water into steam?
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
What is the amount of heat required to raise the temperature of a substance through ten degree Celsius?
One calorie is needed to heat 1 gram of water 1 degree Celsius
What happens when fuel such as coal or gasoline burns?
we release the potential energy to heat energy to do work
Is evaporation heat gain or heat loss?
For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
How are flames produced?
You need four things to create a fire. Fuel (wood, paper, gasoline, rubber, etc.). Heat (From electricity, space heaters, lights, etc.). Oxygen (which is obviously everywhere). And Last, you need a chemical reaction. When fuel, heat, and oxygen mix, all that is needed is a chemical reaction between them and you'll have a fire.
How many joules of heat are needed to completely vaporize 24.40 grams of water at its boiling point?
The answer is 55,117 kJ.
How much heat energy is needed to vaporize g of water at its boiling point of K?
1oo calories for 1 g
What is the amount of energy needed to vaporize one gram of a liquid?
Heat of vaporization
What information does the latent heat of vaporization give?
The energy needed to completely vaporize a mole of a liquid
Why the time needed to vaporize a sample is greater than the time needed to melt a sample?
The amount of time depends on the latent heat of vaporisation and the latent heat of melting.
How much heat is needed to vaporize 100g of water at 100 degrees C?
Heat of vaporization at 100 degrees C is 40.65 kJ/mol. 100g water * 1mol/18.015g = 5.55 mol 40.65*5.55 = 225.6452956 = 226 kJ if three sig figs.
How much heat is needed to vaporize 1.25 kg of ethanol?
The boiling point of ethanol is 78 C but it can evaporate slowly at just room temperature. You can set it on fire and it will vaporize even more quickly.
How much heat is absorbed for 1 kg of liquid gets vapourised into boiling point?
The amount of heat absorbed by 1 kg of liquid to vaporize it depends on what that liquid is, (water?), and what the temperature of the liquid is at the start of the process. Obviously, it will take more heat to vaporize 1 kg of liquid that is at 0º than it will to vaporize 1 kg of liquid that is at, say, 30º.
Mercury can vaporize if heated This means that with enough heat mercury can?
be changed into a gas
Why doesnt the all the water instantly vaporize when you reach the boiling point?
The boiling point is the temperature where a substance BEGINS to vaporize. So all of the water doesn't necessarily need to boil off instantly. To vaporize, molecules of water need to have energy. Only at the boiling point do they have enough energy to boil away, and when they do, they carry this energy with them. This means that a constant supply of heat for a certain period of time is needed for all water in a sample to boil off.
What happens to water when heat is added?
When heat is added to water the molecules move faster and faster until the water reaches it's boiling point and starts to vaporize.
Why heat is needed to boil water?
Because heat changes the temperature of the water
