Question

distinguish between atmospheric pressure and air pressure in the cycle tyres ​

Answer 1

⭕What the difference between air pressure and atmospheric pressure?

✔Air pressure is what you measure with a tire gauge. Atmospheric pressure is what you measure with a mercury barometer. Pressure is the amount of force per unit area that a gas exerts on a surface. If the pressure on both sides of the surface are equal then the relative pressure is zero
