Explain why hotter air rises in the atmosphere

Chemistry

Hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air much like wood floats on water because wood is less dense than water.

The total pressure in a tank fill with a mixture of gasses : Oxygen, Helium, and Argon is 15.3 atm. The phe = 3.2 atm , Po= 7.4
Kisachek [45]

Answer:

Partial pressure of Ar = 4.7 atm

Explanation:

Total pressure of a mixture of gases = Sum of partial pressure of each gas

This mixture contains: O₂, He and Ar.

Total pressure = 15.3 atm

Total pressure = Partial pressure O₂ + Partial pressure of He + Partial pressure of Ar

15.3 atm = 7.4 atm + 3.2 atm + Partial pressure of Ar

Partial pressure of Ar = 15.3 atm - 7.4 atm - 3.2 atm

Partial pressure of Ar = 4.7 atm

wariber [46]

Answer:

A glass of mineral water is not pure water.

Explanation:

Pure chemical substances

Pouring water into a glass from a bottle

Food and drink may be advertised as ‘pure’. For example, you may see cartons of ‘pure orange juice’ or ‘pure mineral water’. This means that nothing else was added to the orange juice or mineral water during manufacture. However, these substances are not pure to a scientist. In science, a pure substance contains only one element or compound.

Mineral water is mostly water, but there are other substances mixed with it. These are the ingredients that you see listed on the bottle’s label.
