A chemical nerve agent that affects the central nervous system.
Example of solid changing toliquid:when you take an ice and put it to thaw out it changes to water (liquid) and is the same for liquid to solid; you freeze water(liquid) and it turns to ice (solid)
It is called melting when a solid turns into a liquid
When a solid turns to a liquid, such as ice turning to water, it is commonly called melting. The solidification of a liquid to a solid is called freezing.
LIQUDIFCATION!!!!!!!! Change of phase; the process is called melting.
Simply, the melting point. Think of an ice cube. The melting point is the temperature at which the ice cube MELTS into a liquid.
it is purify
it is purify
One possibility would be... purity
Purify
solid before it melts?
It would be solid before it reached the melting point. If it is liquid, it has already reached the melting point.
Filter paper is a poor material for powdering a solid before introducing it into a melting tube because it is not abrasive enough to effectively break down the solid into a fine powder. The pores of the filter paper may also retain some of the solid, reducing the amount of substance that can be transferred to the melting tube. Additionally, the filter paper itself may contaminate the solid material being powdered.
Melting is the change from solid to liquid.
It turns from a solid to a liquid
It burns before melting.
This is the melting point.
Freezing is usually when something is turning cold, and solid. Melting is usually when something is turning hot, and into a liquid. Sometimes, depending on chemicals, their can be exceptions to those.
