Yes, it becomes liquefied natural gas (LNG) and is frequently transported by tanker trucks in this form.
No. It takes a combination of pressure and temperature to liquefy some gases. Hydrogen and helium were the last gases to be liquefied and that was with pressure and extremely low temperature.
A gas under normal pressure. Methane has a boiling point of -1600C. It does depend on the pressure at extemely high pressures methane will be a liquid.
A solution under a high pressure
A solution under high pressure will have more gas dissolved into it.
A solution under high pressure will have more gas dissolved in it than one under low pressure.
When gases are operated under very high pressure and extremely low temperatures, they get liquefied.
Light hydrocarbons (methane, ethane, propane, butane, etc.) are generally gases at normal temperatures and pressures. With the exception of methane they can be easily turned into liquids when cooled or stored under pressure. All these gases are present in natural gas or the gas fraction of petroleum oils. They are also created during the fractionation, cracking and reforming processes at refineries. Once liquefied ethane, propane and butane are called. LPGs (Liquefied Petroleum Gases) Methane is not generally considered an LPG although it can be liquefied at high pressures and low temperatures. All the gases come from the same source
by applying high pressure

Yes - low temperature and/or high pressure are needed, how extreme of either depends on the gas.
No, veins are not under high pressure. High-pressure vessels are the arteries.
As Methane Hydrants form at low temperature and at high pressure, they can be found on the seabed and in arctic perma-frost.

You're probably thinking of methane hydrate-clathrate.
LPG stands for Liquefied Petroleum Gas, which means that it is a gas which has been compressed to liquid in cylinders. For more info, go this website: http://en.wikipedia.org/wiki/Liquefied_petroleum_gas
