What is the name given to heat energy at melting point?
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
Is liquid to solid exothermic?
No. Going from solid to liquid at constant temperature is an endothermic process. The required amount of energy is called "heat of fusion" of the material that changes state.
What is the amount of energy required to change a material from a liquid to a gas?
Latent Heat of Evaporation, or Evaporation Enthalpy. It is given in units of energy over unit of mass, i.e., KJ/Kg.
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.
When a solid changes to liquid will it gain or lose energy?
It looses energy to the surroundings. When bindings brakes, energy is released.
Amount of energy it takes to change a material from a solid to a liquid is the heat of?
Heat of fusion.
What do you call the amount of energy needed to change a material from the solid state to the liquid state?
either potential or kinetic
What energy is needed to change a material from a liquid to a solid?
energy
Which material would require the least amount of energy to change 1kg from a solid to a liquid ethanol aluminum propane or water?
ethanol
Do you need the same amount of energy to change a liquid to a gas as you do to change a solid to a liquid?
No, totally independent
What do you call the amount of energy needed to change a material from a solid to a liquid. propane or water?
Heat of fusion. (I have no idea what the "propane or water" part is supposed to mean.)
Energy needed to change a material from solid to liquid?
It is the latent heat of liquefaction.
What type of heat energy is needed to change a material from a liquid to a gas?
endothermic
What energy is needed to change a material from solid to liquid?
Heat energy, usually. However, some substances will change states under the influence of UV or other radiation.AnswerThe energy needed to change a material from a solid to a liquid is called the 'latent heat of fusion', or just the 'heat of fusion'. It is equal to the amount of energy or heat given off by the same material to change it from a liquid back into a solid.Each material has its own heat of fusion. Take solid water (ice) at 0o Celsius, the freezing point. Water's heat of fusion is 79.71 calories per gram. That means that you will need to add 79.71 calories of heat to each gram of ice (solid water) to turn it into liquid water. Interestingly, once that's done, the water will still be at 0o Celsius! The heat was used just to change the water's state from solid to liquid. Once the ice is liquid, then any more heat added will increase the temperature of the liquid, and each calorie of heat will increase the water's temperature about 1o Celsius.This is a similar concept to a material's 'heat of vaporization', which is the amount of energy required to change a liquid to a gas.The amount of heat necessary to change a substance from a solid to a liquid or vice versa is commonly called the heat of fusion. It is more properly known as the standard enthalpy of fusion, or also the latent heat of fusion, or the enthalpy change of fusion. The specific temperature at which the change occurs is defined as the melting point of that substance. A link can be found below.The amount of energy a substance must absorb in order to change from a solid to a liquid is the heat of fusion. A change in which a system absorbs energy from its surroundings is endothermic change.
What phase change will the greatest amount of energy be absorbed by 1 gram of water?
The liquid to gas phase change will absorb the largest amount of heat energy.
