So, if fire isn’t a solid, liquid, gas, or a plasma, what does that leave? It turns out fire isn’t actually matter at all. Instead, it’s our sensory experience of a chemical reaction called combustion. In a way, fire...
Is water vapor a gas or liquid? Water vapour iswater in gaseous instead of liquid form. It can be formed either through a process of evaporation or sublimation. Unlike clouds, fog, or mist which are simply suspended particles of liquid water in the air, water vapour itself cannot be seen...

In contrast, the vapor above the liquid surface becomes denser as the evaporated molecules are added to it. The combination of temperature and press at which the densities become equal is called the critical point. Above the critical point the liquid and the gas can no longer be distinguished;...
The difference between a liquid and a gas is obvious (1)___ the conditions of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and (2)___it to the level of a free surface. A gas forms no free surface but (3)___to ...
The difference between a liquid and a gas is obvious under the conditions of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and fill it to the level of a free surface. A gas forms no free surface but tends to diffuse(...

Do all liquids have a vapor pressure? What about solids? What is boiling point elevation and why does it occur? Which will have the higher vapor pressure at a given temperature: NH3 or PH3? Explain. What happens when the vapor pressure of a liquid is equal to atmospheric ...
" is to say it's a gas. Or, you can say it's mostly gas, with a smaller amount of plasma. Different Parts of a Flame There are several parts of a flame; each is made up of different chemicals. Near the base of a flame, oxygen, and fuel vapor mix as unburned gas. The compos...
