Atmospheric Pressure (GCSE Physics)

When a pilot climbs to higher altitude, what happens to the absolute atmospheric pressure and why might passengers’ ears ‘pop’?

A sealed tyre gauge reads 220 kPa gauge. What is the approximate absolute pressure if atmospheric pressure is 101 kPa?

A student measures the force of the air on a square plate of side 0.50 m. If atmospheric pressure is 1.02 × 10^5 Pa, what is the force on the plate?

Why do we need to know atmospheric pressure when calibrating sensitive laboratory balances?

Why does atmospheric pressure decrease as altitude increases?

What is the SI unit of atmospheric pressure?

A closed container at sea level has absolute pressure Pabs. If we define gauge pressure Pg = Pabs - Patm, what is Pg when the container is evacuated to perfect vacuum?

Two students compare pressures: Student A says atmospheric pressure is the same in all directions at a point. Student B says pressure acts only downward. Which is correct and why?

A weather map shows two neighbouring areas: a small steep pressure change over a short distance and a wide gentle pressure change elsewhere. Where will the wind be strongest?

A sealed syringe contains trapped air. If the plunger is pushed slowly reducing the volume but temperature is kept constant, what happens to the pressure inside?

A student uses a syringe with a sealed tip and records pressure as they push the plunger in slowly at constant temperature. Which gas law applies to explain the observed pressure change?
