liquids heat, the evaporate to tiny droplets called water vapour. evaporation takes place when heat levels rise into an approx of 20-30C. The higher the heat level is the faster the liquids evaporate. But if you leave something outside like syrup for sometime, it will take much more longer to evaporate since syrup has a substance so much thicker than water.
lets say you have a cup of water that is cold. when the air at roomtemperature hits the glass (look below) the air condenses because it is cold. this forms little drops on the outside of cup. this continues till the water is at room temperature them the water proceeds to evaporate.
(When a temperature is warm molecules spread out and when they are cold they condense.)
Liquids are a collection of molecules or atoms found to be at a liquid state at a certain temperature (usually room temperature).
They are said to be liquid because of how closely the atoms or molecules are collected (solids are tightly packed and gases are losely spread, liquids are somewhere in between).
By heating a substance, you can excite the atoms or molecules because the heat gives them extra energy to move about. By heating the substance, you give the atoms or molecules the opportunity to spread further out (like gases).
For example, water has a boiling point of 100 degrees celcius, which is where it changes from a liquid to a gas because its particles have become 'engergised' enough to become gas-like.
So in conclusion, most liquid do need to be heated to evaporate (to become gases). However some solids sublime (where they go from solid to gas without becoming liquid), like dry ice.
ANSWER
Many liquids will evaporate easily just by being exposed to the open air. Think of laundry on a clothes line. Or spill out some alcohol on a dish. The oceans and lakes are continually evaporating as part of our rain cycle. Heating or exchanging the air (fanning) will make the process go more quickly.
Yes, liquid evaporate when they are heated
heat helps trehe liquid to evaporate as the kinetic energy of the molecules increases due to which molecules move faster and reach the surface .thus liquid evaporates
Evaporation is an exothermic process.
All juices if they are fully liquid (and 0 percent thick) can evaporate
All liquids would evaporate if heated to a high enough temperature.
Yes and no. For practical purposes most all liquids will evaporate over time. Technically, you can create a controlled environement to eliminate evaporation.
they all contract.
They are used to evaporate liquids. Specifically, the goal is to separate the fluid from any dissolved solids therein. Lets say you want to get salt out of water- you can't drain them by hand, so you evaporate the water, which leaves the salt there.

Brownies do not evaporate. Only liquids evaporate.
All liquids would evaporate if heated to a high enough temperature.
Violate liquids are liquids that will evaporate, or vaporize easily. They evaporate at room temperature. Violate liquids have a low boiling point.
evaporate
I think a better question would be, what liquids DON'T evaporate in sunlight. I believe the answer to that question would be mercury.
Liquids differ in the rate at which they evaporate.
No, each liquid evaporate differently.
Gases don't evaporate, liquids do.
A liquid that is slow to evaporate.
