aha! pub-quiz time again!
well, the gas you put in you car is a liquid, the gas in the gas-pipes is a gas, *but* GaS is a solid! (that's gallium sulphide for all you non-chemist types!)

There are three phases of matter; solid, liquid and gas. A solid may have multiple facets. A liquid has only one surface. A gas lacks a surface. A Phase change occurs when a solid is made to melt. this takes heat energy but the temperature stays constant. Similarly another phase change occurs when a liquid "boils" or evaporates to a liquid. Again heat is required but the temperature does not change. Occasionally a solid may change directly to a gas. Frozen CO2 or dry ice sublimates directly to the gas at normal pressures. I don't think you are ready for the pressure effects on phases of matter.

Trick question. A liquid can become a solid or a gas (vapor) if coold or heated. A solid form of gas can be thawed out to become a liquid and then heat may cause it to become a gas...but a gas once it has become a gas is gas...and that "ain't no gas".

I assume you mean natural gas, versus gasoline or gas in general.
Natural gas is a gas that is found within our planet.
The Natural gas we explore is composed of several substances, such as methane, but its composition varies, and has to be treated to remove such things as carbon dioxide and hydrogen sulfide before it can put into a pipeline.
The substances that make up natural gas are present in the earth as a liquid when the pressure is very high, and becomes a gas as pressure is reduced on its way to the surface.

Gasoline is a liquid at room temperature (20 deg C). But it will exist as a vapor if you heat it above 80 deg C or something. If you cool gasoline enough, (very very cold temperatures -100 deg C) I suspect it will turn into a wax like solid.
The phase of a substance depends on both temperature and pressure. If you are really interested you could try searching for a gasoline phase diagram.

Technically gas is a gas, which as an advanced fluid state so that it shares some liquid properties but is neither a liquid or solid by definition.

It is a gas. Gas is one of the states of matter.

gas can be convert to liquid by low temp and can convert to solid with lower temp.

Umm Gas is a Gas

No,a gas is a gas,it hasn't got a predefined form or structure
