A pressure switch contains gas behind a sealed flexible membrane. The force exerted on the membrane remains steady rather than occurring as separate jolts.
Which process produces this steady force on the membrane?
Each particle pushes on the membrane continuously while moving through the gas.
One collision produces a force that remains steady while the gas is sealed.
All the particles strike the membrane together at regularly spaced times.
An enormous number of collisions occur each second, and their effects add together.
