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 is the heat energy needed to change a liquid to gas while the temperature stays the same?
(latent) heat of vaporization
Latent heat is the energy required for 1 kg of a substance to change?
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
If heat energy is needed to change phase from a solid to a liquid List the possible sources of the heat needed for this phase change in your baggie Which source do you think is the possibility and why?
The ice, the milk, the salt, the air in the baggie, the heat from your hands. The milk is the best source of heat energy for the melting process because it is a liquid and stores more energy for the phase change than the air or salt do. Your hands do not touch enough area to be effective sources of heat. ~*~
What is the difference between heat of fusion and heat of vaporization?
Latent heat is the amount of thermal energy required to change the phase of a substance. Latent heat of fusion is the amount of energy needed to change it from a solid to liquid or a liquid to solid, and the latent heat of vaporization is the thermal energy needed to change from a liquid to gas or a gas to liquid. For example, in the equation Q = mL, Lfusion (latent heat of fusion) for water is 75.5 cal/gram. Lvaporization (latent heat of vaporization) for water is 539 cal/gram. Substances have different latent heats.
What energy is needed to change a material from a liquid to a solid?
energy
Energy needed to change a material from solid to liquid?

endothermic
Energy needed to change a material from solid to liquid 3 WORDS?
Heat of Fusion
What energy is needed to change a material from a liquid to a gas?
Usually heat is needed. but this can happen through osmosis as well.
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 is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
What is the energy needed to chage a material from a liquid to a gas?
heat of vaporization
Energy need to change a material from liquid to gas?
You can add heat and cause liquid to gasify. Or you can decrease the pressure in the system and cause liquid to gasify. Note that you may gasify liquid and leave suspended or dissolved solids behind. More heat or pressure may be required to convert these remnants to liquid and then gas.
What is the substances in food that gives the raw material and the energy needed by the body?
liquid
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.)
What energy needed to change 1 kg of liquid into gas at boiling point?
Thermal Energy
