Liquefied Natural Gas

Explanation:

Gases are usually liquefied in the downstream sector during crude processing. These natural gases are products of distillation of crude oil in fractionating columns. Some of them are also found in geological formations.

  • To easily transport these gases, they are liquefied in vessels that carries them from one place to another.
  • Liquefaction is the process of converting a gas or solid into a liquid form.
  • Gases are usually compressed under very high pressure into vessels through which can make them easier to transport.
  • Gases do not have a fixed volume and they typically assume the volume of any container they are taken into.

Maksim231197 [3]

The mass of the sample reported is 3.5465 g option e is correct.

Mass is the quantitative measure of the physical body.

The mass of the empty sample container is given as 12 g.

The mass of empty as well as sample containers is given as 15.5465 g.

Therefore, the mass of the sample will be given as :

Mass of sample = mass of a sample as well as empty containers - a mass of empty sample container

  = 15.5465 - 12

  = 3.5465 g

Therefore, the mass of the sample reported is 3.5465 g option e is correct.
