What happens to acetic acid when it melts?

Answer 1

its H2O , two parts hydrogen one part oxygen otherwise known as water

Now all matter (stuff that exists) has different states but is the same material

What state the matter is in is dependent on several things some as pressure and temperature

Under normal atmospheric pressure water will change states from a solid to liquid at temperatures above 0 degree Celsius.

The states of matter are based on the energy and structure of the chemical bonds, at lower temperature there is less energy and more rigid bonding which causes a solid to be well solid

At higher temperature there is more energy and the bonds move more and are no longer able to maintain a rigid structure and they turn to a liquid and even high temperature the bonds gain even more energy and bonds break and state becomes a gas

So ice,liquid water, and steam are the same thing H2O just each at a different energy state

Answer 2

Acetic acid is a liquid at room temperature so it can not be melted.
