Question

Define humidity. Explain the use of nitrogen and oxygen gas in our day-to-day life.​

Answer 1

Humidity is the concentration of water vapour present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest.

Due to these properties, the nitrogen is used in food industry, steel processing, electronics and similar applications. Oxygen is also without colour, odour and taste. Compared to nitrogen the oxygen reacts with most of the chemical elements. It is necessary for most living organisms for metabolic processes.

Answer 2

Answer:

Humidity is the amount of water vapor in the air

the nitrogen is used in food industry, steel processing, electronics and similar applications.

nitrogen used = 78%

oxygen use = 21%
