A sealed tyre gauge reads 220 kPa gauge. What is the approximate absolute pressure if atmospheric pressure is 101 kPa?
Which instrument directly measures 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?
Which of the following is a correct statement about gauge pressure?
A diver at 10 m depth underwater experiences pressure from the water. Which contributes most to that pressure?
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?
Why do we need to know atmospheric pressure when calibrating sensitive laboratory balances?
A vacuum pump reduces pressure inside a chamber. Which statement about the remaining gas is true as pressure falls?
Why do meteorologists use station pressure corrected to sea level?
A hydraulic jack uses a small-area piston with force F1 to produce a large force F2 on a larger-area piston. Which principle explains this?
What is the SI unit of atmospheric pressure?
