and chilling until the mixture freezes and forms solid crystals. To then discover the melting point of the newly formed acetaldehyde phenylhydrazone, you have to re-melt it. This is where the ...

All substances will change state at specific temperatures, known as their melting and boiling points. Many substances can exist as solids, liquids or gases, which are all different states of matter.

For the snow to disappear, it will have to turn from its solid state to liquid water. According to HeatTrak, the melting point of snow is 32 degrees Fahrenheit or zero degrees Celsius.

It's melting point is about 85 degrees, so with just a little heat, you can turn it from a solid, crystal-like state into a fun, reflective pile of goo. Here's a look at a few of its properties ...

Ohio was hit with a sheet of snow. When will the snow go away? Here's the science behind it and the forecast that will keep Ohio covered in snow.
