Pressure is the amount of force pressing on something. Air pressure is the force with which air presses. The force comes from the bombardment of the moving air particles.
A compelling or refracting influence ie. peer pressuere.
apex- the force of gas molecules hitting their container
Pressure is the continual physical force that is exerted against an object. The amount of force acting per unit area is called pressure

What effect does adding a solute have on the boiling point of a solution
🔄 Click to see definition
Definition1/19
Adding a solute to a solution, or some liquid, causes the
boiling point to increase.
Think about water, sometimes people throw salt in their water
when they're boiling noodles. This causes the boiling point to
increase so the water is actually at a higher temperature (although
most of the time the amount of salt added isn't nearly enough to
cause any measurable change).
