Answer 2

Answer:

1) When we take out air through this instrument, we make the place inside it a vacuum because we took the air out and if we are applying it to a glass of water or juice or any liquid or gas, the water is coming up to fill the vacuum because of air pressure.

2) When we fill the tire let us understand that there are some vehicles that are optimized by using wheels that are inflated at different pressure levels (atmospheres), depending on the manner in which they will be used (e.g., mountain bikes – low pressure, racing bikes – high pressure).
