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 else can I help you with?
In a nuclear power plant what is used to change water into steam?
Heat from the nuclear reaction changes water to steam.
Solid ice will change to liquid water and then to gaseous steam when you add what?
Energy because energy can be used as heat.
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 do you recover geothermal energy?
After drilling into the Earth to the heat, it is used to turn water to steam, to turn a turbine.
What makes steam-fired?
When water heats up to the point where it starts to boil, steam will descend from the water. So, water and high temperatures create steam. But, since other liquids also can create steam, I would say that if you boil a common liquid you will get steam.
What form of energy from the burning of refuse changes water into steam?
Heat energy.
In a nuclear power plant what is used to change water into steam?
Heat from the nuclear reaction changes water to steam.
When energy transformation most likely occurs in a steam iron?
Energy transformation in a steam iron occurs when electrical energy is converted to thermal energy in the heating element. This thermal energy is then transferred to the water in the iron's reservoir, causing it to evaporate and turn into steam. The steam, in turn, transfers heat energy to the fabric being ironed, enabling the smoothing process.
How hot water changes to steam is?
When water is heated, the energy from the heat causes the water molecules to move faster and break free from the liquid phase, forming steam. This process is known as evaporation. As more heat is applied, the water molecules gain enough energy to overcome the intermolecular forces holding them in the liquid phase, resulting in a phase change from liquid water to gaseous steam.
What is the energy released when steam condenses to water?
The energy released when steam condenses to water is called the latent heat of vaporization. This energy is released in the form of heat as the steam loses its thermal energy and transitions back into liquid water.
How can steam changed back into water?
By removing heat energy from the steam.
What energy changes take place in the boiler?
In a boiler, potential energy from fuel is converted into heat energy through combustion. This heat energy is then transferred to water, raising its temperature and converting it into steam. The steam carries this thermal energy to turbines, where it is converted into mechanical energy to generate electricity.
Is conversion of steam to water an exothermic reaction?
Yes, the conversion of steam to water is an exothermic process. When steam condenses into water, it releases heat energy to the surroundings. This heat energy is given off as the steam loses its kinetic energy during the phase change.
Does Boiling Water increase heat energy?
Boiling water involves converting liquid water to steam by adding heat energy. The heat energy increases the temperature of the water until it reaches its boiling point, at which point the water vaporizes into steam.
What type of energy is atomic energy?
Heat. The heat boils water to create steam to drive steam turbines to generate electricity.
Does energy flow into or out of water when it is turning into ice?
It must flow out, ice contains less energy than water. You just have to remember that heat is energy, and all energy, no matter what form, eventually winds up as heat. Take heat energy out of water, it gets cooler, and eventually freezes. Add heat energy to ice, it first changes state to liquid, and then starts to get warmer. Keep adding heat energy to it, it keeps getting warmer and warmer. Keep additing heat energy to it, and eventually it changes state to gas ... called "steam". Take heat energy out of the steam, it first changes state to liquid, then gets cooler. etc. etc.
