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.

Does condensation need heat energy?
Condensation releases energy rather than absorbing it, this is the latent heat of the change of state from liquid to gas and vice versa

Is liquid a form of energy?
ok i need to know how heat effects liquids
Do you have to remove energy form liquid to make it a solid?
The process of freezing, by which a liquid changes to a solid, technically doesn't require energy. In practice, if you have to make icecubes in your freezer, you do use energy - but the energy content of the ice is still lower than that of the water. Freezing happens by losing energy, not by gaining it. Whereas melting a solid into a liquid does require energy.
How is heat transfered by radiation different from conduction and convection?
Radiation does not need any material medium to transfer energy where as the other two conduction and convection need a material medium to perform.
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 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.
Do you need to increase or decrease the amount of heat energy to change a solid to a liquid?
Thermal (heat) energy must be added or removed in order to cause a change of state.
To change liquid to a soild?
To change a solid to a liquid you need to add energy. The energy makes the molecules vibrate faster and they find it easier to break bonds holding them to the molecules directly next to them and form new bonds to other molecules.
What kind of material you need to change sun light to electric?
black material to absorb the light energy and then more steps follow until electricity is produced.
Does condensation need heat energy?
Condensation releases energy rather than absorbing it, this is the latent heat of the change of state from liquid to gas and vice versa
Does the mass of liquid affect the rate of temperature change?
Sure. Other things being equal, you need more energy to raise the temperature of a larger mass of liquid.
To change a gas to a liquid?
* To change a gas into a liquid you need to evaporate the gas by heating it
Does condensation need heat?

What does water vapor need in order to change states from a gas to a liquid?
Water vapor needs to condense by cooling it.
Does potential energy increases or decreases when gas changes to liquid?
The potential energy of a substance decreases when it changes into a liquid. This is because it's losing the heat energy it had when in gas form to become liquid.
What tool is used to measure when a liquid becomes a solid?
Eyes and sense of touch,Ice pick.A More Technical Perspective:In a laboratory setting the change of state between a liquid and a solid is marked by a loss of heat energy while the temperature of the material remains the same. This is due to the energy surrendered by the material as its molecules take on a more "energy economic" configuration. As a consequence the devices need would be a thermometer to measure temperature change and a calorimeter to measure the rate of heat loss.Alternately the freezing point could be determined by plotting temperature change (with a thermometer) with time in a constant temperature bath. The freezing point would be marked by a flat section in the graph as heat was released by crystallization rather than heat lost due to heat capacity.
