What is the pressure in gas?

to find the pressure in gas

use the formula

pV = nRT

where p is the pressure in Pa (pascals; Si unit)

V is the volume in m^3 (meters cubed; Si unit)

n is the number of moles

R is the gas constant which is 8.31

T is the change in temperature (the unit for this doesn’t really matter,but it depends on your curriculum I think)

check your school’s specifications for this subject so that you know which units to use

i listed the Si (standard international) units, which is what i use at my school as per the specifications.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
