Ammonia is made by haber process. We can turn it to liquid by high pressure and low temperature.
Ammonia (NH3) is easily liquefied compared to hydrogen chloride (HCl) because ammonia has weaker intermolecular forces (hydrogen bonding) compared to the strong dipole-dipole interactions in hydrogen chloride. Weaker intermolecular forces result in easier liquefaction of the gas.
Melted/Liquified
99.95%(pure ammonia) or better is Refridgeration grade ammonia.
Ammonia is a gas - it can't be "straight".
Ammonia is a noun.
Milk is a liquid
LIQUIFIED NATURAL GAS
Liquified Petroleum
putting it in liquified gas.

Liquified nickel and iron.
Yes, Liquified Petroleum Gas is a Gas. It is a mixture of butane and propane. Also ethyl mercaptan is added to LPG to detect the gas leakage.
carbon dioxide
Oxygen is not flammable but is necessary for combustion.
Melted/Liquified
LPG is Liquified Petroeum Gas
The three main groups of compressed gases are Dissolved, Liquified and Non-Liquified gases. You can learn more about gases and compressed gases at the Wikipedia website.
