which among the following gases can be liquefied easily?

In the present case, NH3 has highest 'a', can most easily be liquefied. Higher is the critical temperature of a gas, easier is its liquefaction. This means that the intermolecular forces of attraction between the molecules of a gas are directly proportional to critical temperature of the gas.

Liquid nitrogen is the liquefied form of the element nitrogen that's produced commercially by the fractional distillation of liquid air. Like nitrogen gas, it consists of two nitrogen atoms sharing covalent bonds (N2). Sometimes liquid nitrogen is denoted as LN2, LN, or LIN.

A real gas can be liquefied when cooled below critical temperature under application of pressure. The critical temperature of a gas is the temperature below which it can be liquefied by the application of pressure.

The mere existence of solid noble gases may come as a surprise to some readers. ... The noble gas helium, the most difficult of all the elements to liquefy and solidify, was first liquefied by the Dutch physicist Heike Kamer lingh Onnes in 1908.

One Big Happy LPG Family Both propane and butane, along with isobutane, are all hydrocarbon gases that fall under the broad label of "LPG", as they are all liquefied petroleum gases. They are a group of flammable hydrocarbon gases that are liquefied through pressurisation and commonly used as fuel.

Properties and reactions Propane is a colorless, odorless gas. At normal pressure it liquifies below its boiling point at −42 °C and solidifies below its melting point at −187.7 °C. Propane crystallizes in the space group P21/n.

Propane is also known as LPG - liquefied petroleum gas – or LP gas. Propane gas is naturally odourless so odourant is added for leak detection.

LPG is short for Liquified Petroleum Gas. LPG can be Propane, Butane isobutane and can be a mixture of these gasses. In the United States, LPG is thought of as propane but while propane is a LPG, not all LPG is propane. ... LNG is natural gas that has been cooled to a liquid state at -260°.

Butane, a highly flammable, colorless, easily liquefied gas used in gas-type lighters and butane torches. Naphtha, a volatile flammable liquid hydrocarbon mixture used in wick-type lighters and burners. Charcoal lighter fluid, an aliphatic petroleum solvent used in lighting charcoal in a barbecue grill.

CNG is not to be confused with liquefied petroleum gas (LPG). The main difference between these gases is that LPG is stored as a liquid, fuelled at 8-10 bar, and is heavier than air. CNG is compressed to 250 bar and is gaseous and lighter than air.

Answer: (c) Low temperature and high pressure are required to liquefy gases to liquids. There is a lot of space between the particles of a gas. On applying high pressure, the particles of gas move get so close that they start attracting each other sufficiently forming a liquid.

Gases become more difficult to liquefy as the temperature increases because the kinetic energies of the particles that make up the gas also increase. ... The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied.
