The molecules in a gas are moving in all directions and they constantly crash into the surface and bounce back. This is just like when you throw a tennis ball against a wall and it bounces back: the wall changes the momentum of the ball by changing its velocity, meaning the wall exerted a force on the ball and, by Newton's laws, the ball exerted an equal and opposite force back on the wall (just the wall is so massive it doesn't show it). With air molecules this happens many many times, so this collectively exerts a pressure (which is just a force per unit area) on whatever surface is in contact with the gas. This pressure just depends on the temperature of the gas and how compact it is (its volume).
What else can I help you with?
How do you increase the pressure being applied to an object?
To increase the pressure being applied to an object, you can either increase the force being applied to the object or decrease the area over which the force is distributed. This can be achieved by exerting a larger force on the object or decreasing the surface area in contact with the object.
How do you describe two ways to increase the pressure exerted on an object?
To increase the pressure exerted on an object, you can either decrease the area over which the force is applied or increase the force applied on the object. This can be achieved by either applying a greater force on the same surface area or applying the same force on a smaller surface area.
How does pressure exerted by a solid object?
Pressure exerted by a solid object is calculated by dividing the force exerted by the object over the surface area on which it is applied. The formula is pressure = force / area. The pressure increases as the force increases or the surface area decreases.
What depends on force and area?
Pressure depends on force and area. Pressure is the force applied perpendicular to the surface of an object per unit area. The formula for pressure is Pressure = Force/Area.
What is a force that relates to the amount of force put on a given surface called?
The force that relates to the amount of force put on a given surface is called pressure. It is calculated by dividing the force applied to an object by the area over which the force is applied.

What does the pressure on a surface depend on?
The pressure on a surface depends on the force applied perpendicular to the surface and the area over which the force is distributed. It is calculated as the force divided by the area. The pressure increases with increasing force or decreasing area.
When the force applied on an object is doubled how does the pressure applied on an object change?
It will be double, if the area is unchanged. pressure=Force/area
Is pressure a contact force?
Yes, pressure is a contact force that occurs when an object comes into contact with a surface. It is the force applied perpendicular to the surface per unit area.
Is pressure the amount of force that acts on a given area of an object?
Yes, pressure is the amount of force applied per unit area of a surface. It is calculated by dividing the force acting on an object by the area over which the force is distributed.
What is the relation between force and area?
Pressure is the force over an area applied to an object in a direction perpendicular to the surface. p = F / A where:p is the pressure,F is the normal force,A is the area.
What two things do you need to know to calculate pressure?
To calculate pressure, you need to know the force applied on an object and the surface area over which the force is distributed. Pressure is calculated by dividing the force by the surface area.
What kind of force is pressure?
Pressure is a force applied perpendicular to the surface of an object due to the contact with another object or fluid. It is measured as force per unit area and can cause deformation or compression of the object it is applied to.
