What is gas give two example?
Examples of gases are oxygen at room temperature (approximately 20 oC or 68 oF), hydrogen at room temperature, and water at standard atmospheric pressure and a temperature above 100 oC or 212 oF. When a sample of matter in the gaseous state is heated, the atoms or molecules gain kinetic energy and move more rapidly.
What is an example of gas to liquid?
Examples of Gas to Liquid (Condensation)
Water vapor to dew – Water vapor turns from a gas into a liquid, such as dew on the morning grass. Water vapor to liquid water – Water vapor forms water droplets on the glass of a cold beverage.

How do you classify gases?
Hazard classification
Compressed gases are classified as class I, II, III, or IV in order of decreasing hazard . * Classes are based on the lethal concentration to 50% of test animals (rats) of each gas (LC50).
How do we use gas in everyday life?

What are the 5 components of air?
Components of Air – Nitrogen, Oxygen, Carbon Dioxide, Water Vapor and Other Gases .
Which gas is used in air conditioner?
Freon is a non-combustible gas that is used as a refrigerant in air conditioning applications. This freon undergoes an evaporation process over and over again to help produce cool air that can be circulated throughout your AC system.
What gases are combined in air?
Air is mostly gas
It's a mixture of different gases. The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen . Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
