Question

What is barometric pressure in physics?

Answer 1

Barometric pressure:

1. In physics, barometric pressure (also known as atmospheric pressure) is the pressure contained within the Earth's atmosphere.
2. The standard atmosphere is defined as a unit of pressure with a value of 1013.25 millibars or 101325 Pascals.
3. The symbol 'atm' is frequently used to represent the standard atmosphere.
4. It is important to note that the unit of atmospheric pressure is equivalent to the mean of the planet's sea-level atmospheric pressure.
5. As a result, the atmospheric pressure on Earth is approximately equal to 1 atm. In most cases, the atmospheric pressure can be closely approximated using static pressure, which is caused by the weight of the object.
