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?
The heat energy needed to change a liquid to gas while the temperature stays the same is called the heat of vaporization. This energy is used to overcome the intermolecular forces holding the liquid molecules together and convert them into a gas. It is a phase change process that occurs at the boiling point of the substance.
Is energy flow involved in a change in state?
Yes, energy flow is involved in a change in state. When a substance changes state, such as from solid to liquid, energy is either absorbed or released. This energy is needed to break the bonds between molecules in the solid state or to form new bonds in the liquid state.
What is the energy required to go from liquid to gas called?
The latent heat of vaporization
What is the difference between the heat of fusion and the heat of vaporization in terms of their effects on phase changes?
The heat of fusion is the energy required to change a substance from a solid to a liquid, while the heat of vaporization is the energy needed to change a substance from a liquid to a gas. Both are types of phase changes that require specific amounts of energy to occur.
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?
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 a liquid to a gas?
Usually heat is needed. but this can happen through osmosis as well.
Energy needed to change a material from solid to liquid 3 WORDS?
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 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.
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 energy needed to chage a material from a liquid to a gas?
heat of vaporization
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?
The amount of energy needed to change a material from a solid to a liquid is called the latent heat of fusion. This value differs for different substances, but for water, it is 334 joules per gram, while for propane it is 93 joules per gram.
What energy needed to change 1 kg of liquid into gas at boiling point?
