What happens when you apply heat to a liquid?

Answer 1

When you heat a liquid it causes a reaction this is called evaporation.The liqui9d then turns in to a gas

As it turns into a gas, the liquid boils. The temperature at which it boils is called the boiling point and is a constant if the pressure stays the same. Until the boiling point is reached nothing interesting happens to liquid while it heats.

Answer 2

First off you have to know why a liquid is a liquid. There are five "states" or "phases" of matter, the three most common being solids, liquid, and gases. There are many factors that determine the phase of a substance, temperature being one of the biggest. A substance changes its phase when its molecules become more or less active. Typically when a substance is heated the molecules become more active and begin to bounce off of each other and the amount of space between them increases forming a looser bond. Conversely, when you cool a substance its molecules usually become less active and they rest more tightly together in a more fixed position next to each other.

Liquids can produce different effects when being heated depending on its chemical makeup but if you're looking at a singular substance you can usually count on the molecules getting farther and farther apart until you form a gas. If you're looking at a mixture of two or more substances you might add enough energy (heat) to trigger a chemical change. During a chemical change the molecules of the substance change to gain, lose, or exchange atoms to create an entirely new substance as opposed to phase changes which are entirely physical. For example you can freeze, melt, and boil a cup of water all you want but in the end you'll still be able to get your water back; however, if you heat a cup of egg whites the change is irreversible.

To answer your question in a nutshell: You're adding more energy to the liquid so it changes its phase or triggers a chemical reaction.

Here's some terminology for phase changes:

• Melt - (Solid -> Liquid) [Ice to Water]
• Freeze - (Liquid -> Solid) [Water to Ice]
• Evaporate (Liquid -> Gas) [Water to Steam]
• Condense (Gas -> Liquid) [Steam to Water]
• Sublime (Solid -> Gas) [Dry Ice to CO2]
• Deposit (Gas -> Solid)

Answer 3

There are many people that heat large amounts of liquids. These people usually have a purpose for needing this liquid heated.

Answer 4

It raise its heat to boiling point. At this point the liqiud will begin to evaporate [turn to gas] until no liquid is left.

Answer 5

sometime liquid turn into gas but if it is something like waster it just stays a liquid

Answer 6

It is a bunsen burner.
