Question

What is pressure? Pressure is the force exerted per unit time by gas molecules as they strike the surfaces around them Pressure is the force exerted per unit area by gas molecules as they strike the surfaces around them Pressure is the force exerted per unit volume by gas molecules as they strike the surfaces around them Pressure is the force exerted per unit length by gas molecules as they strike the surfaces around them What causes pressure? Pressure is caused by bindings of gas molecules with surfaces or other gas molecules Pressure is caused by annotations of gas molecules with surfaces or other gas molecules Pressure is caused by interactions of gas molecules surfaces or other gas molecules Pressure is caused by collisions of gas molecules with surfaces or other gas molecules

Explanation / Answer

1.

Pressure is the force exerted per unit area by gas molecules as they strike the surface around them.

2.

According to kinetic theory of gases,

pressure is caused by collisions of gas molecules with surfaces or other gas molecules
