define LPG, CNG, Matter, diffusion and compressibility
Answers
Explanation:
1. LPG-Liquefied petroleum gas (LPG or LP gas), is a flammable mixture of hydrocarbon gases used as fuel in heating appliances, cooking equipment, and vehicles.
2.CNG-CNG, also known as compressed natural gas, is an eco-friendly alternative to gasoline. Made by compressing natural gas (methane) down to less than 1% of its volume, CNG fuel is safer than gasoline and diesel because it is non-toxic and does not contaminate ground water. This natural gas is the same gas that you use daily to heat your home and water, cook on the stove and even to dry your clothes in a dryer. The use of CNG fuel is becoming more popular with both commercial and non-commercial vehicles.
3.Matter- matter is anything that occupies space and has mass
4.Diffusion- Diffusion is the net movement of anything (for example, atom, ions, molecules) from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration.
5.compressibility-the capacity of something to be flattened or reduced in size by pressure.
