What creates pressure?
Pressure inside of a balloon is created by the movement of the air molecules against the inner surface of the balloon. The more air inside the balloon, the more molecules that are hitting the same surface are, so there is more pressure.
How does a can crush when you heat up the air inside then let it cool?
You must mean a can that you can heat when open and seal air tight when you let it cool. When you heat it the air inside is heated and expands; so the molecules spread out (less molecules=less air). When the can is sealed and cooled, the molecules move together and that creates a vacuum relative to the outside air pressure, and that pressure crushes the can.
Why does pumping a soccer ball with an air pump increase the pressure inside the ball?
Pumping pushes more air molecules into the ball. That makes more molecules moving around inside of the ball and more molecules colliding with the inside of the ball. All of those collisions (trillions and trillions) push the inside of the ball out. When the temperature is increased, the molecules move faster. Faster molecules collide with the inside walls more frequently, which also increases the pressure. You can test this by pumping up a ball then putting it into the freezer and see what happens to the pressure.
Why does a sealed gas balloon expand when it is brought from ground level to the top of a mountain?
the air is less dense at altitude, therefore it exerts less pressure. the gas in a sealed balloon will exert the same pressure regardless of it's altitude, so, with less outside pressure to overcome, the balloon will expand.
What is the definition of atmospheric pressure?
Air pressure is the force (weight of Earth's atmosphere) exerted on you by the weight of tiny particles of air, the air molecules above and around you. This is also referred to as "barometric pressure" (measured with a barometer) and will change with altitude or elevation. The standard pressure is 1 ATM (atmosphere), equal to 101325 pascals or 1013.25 mbar.

Why the volume of the air molecules inside of the syringe changes?
This is the effect of the pressure.
Why is there no gas pressure inside a vacuum?
Gas pressure is caused by the molecules of gas striking the walls of a container, or in the case of Earth's atmosphere, the molecules of air hitting the earth. In a vacuum, there are no gas molecules. No molecules, no pressure.
If the pressure inside the lungs decreases outside air is pushed into the airways by what?
The pressure inside the lungs decreases as the ribcage moves out and up. Air from outside basically gets pushed in by other air molecules due to the pressure gradient (air moves from a high pressure to a low pressure)

How are molecules and air pressure connected?
Air pressure has molecules in it but other than that their is no connection
When air is heated air pressure decreases because the molecules?
when air is heated ,air pressure decreases because the molecules are
Air pressure is affected by temperature.?
Yes, air pressure is affected by temperature.When the temperature is higher the air pressure lowers and the weight of the air is lower. When air is warmer the molecules sperate and there are less molecules that can cause pressure.
Why does an increase in the number of molecules increase the pressure?
The great the density the higher the air pessure.
Why does a balloon get smaller in cold weather?
The simple answer is because the pressure remains the same. When pressure remains constant, the change in volume will be directly proportional to the change in temperature. The air molecules release energy as they travel around inside the balloon. What we call pressure is technically the force of the air molecules colliding with the inside of the balloon and each other. The kinetic energy is related to the speed of the molecules. The faster the molecules are moving, the greater the kinetic energy. The greater the kinetic energy, the greater the pressure in the inside of the balloon. The outside air is doing the same thing to outside of the balloon. Therefore, the pressure pushing out is equal to the pressure pushing in. Temperature decreases because the molecules inside the balloon are releasing their energy in the form of heat as they interact with each other. In fact, they heat energy passes through the balloon and is absorbed by the air on the outside. Over time, more energy is released, and the temperature drops. The volume of the balloon decreases in order to maintain a constant pressure. As the surface area decreases, the total pressure pushing in also decreases so that it always equals the pressure pushing out.
Air pressure becomes lowet as water molecules are addrd to the air because water molecules?
Air pressure becomes lower as water molecules are added to the air because water molecules have less weight.
