Question

What is pressure?Express some everyday observations where this phenomenon is used.

Answer 1

Answer:

Explanation:

The mathematical definition of pressure is force per area and the SI unit of pressure is pascal (Pa). Air pressure is something we all experience everyday. The air pressure on a person is the weight of the air being acted upon by gravity on to the person. Luckily the body has an internal pressure that cancels the air pressure which i why we don’t collapse due to the weight of the air.
