What happens to particles in a balloon?
Inside the balloon, the gas particles collide with the balloon’s inner walls. As the molecules heat up, they move faster and strike the inside wall of the balloon harder. This increased motion of the gas particles increases the force on an area of the balloon, producing a rise in the pressure.
How do air particles inflate a balloon?
Blowing up a balloon involves forcing additional air particles from your lungs into the balloon. These particles hit the inside walls of the balloon creating enough air pressure to force the rubber of the balloon to expand and the balloon to inflate.
How do gas particles move in a balloon?
Gases, such as the air or helium inside a balloon, take the shape of the containers they’re in. They spread out so that the space is filled up evenly with gas molecules. The gas molecules are not connected. This means they move faster and have more frequent and harder collisions inside of the balloon.
How do gas particles move?
In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster. In liquids, particles are quite close together and move with random motion throughout the container.
Did the air from the balloon hit anything to make the balloon move?
When the neck of an inflated balloon is released, the stretched rubber material pushes against the air in the balloon. The air rushes out of the neck of the balloon. The action of the air rushing from the balloon pushes against the balloon, moving it in the opposite direction.
How do air molecules move?
Air is made up of molecules that are constantly in motion. As air warms up, the molecules start to vibrate and bump into each other, increasing the space around each molecule. Because each molecule uses more space for motion, the air expands and becomes less dense (lighter).
What are three characteristics of particles in a gas?
Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.
What made the balloon move?
The air trapped inside the balloon pushes out the open end, causing the balloon to move forward. The force of the air escaping is the “action”; the movement of the balloon forward is the “reaction” predicted by Newton’s Third Law of Motion.
How do air particles move?
You can’t change the mass of an air particle, but you can change its speed. By making a particle go faster, you increase its kinetic energy. Air particles can be made to move faster by heating a sample of air. Heat increases the kinetic energy of particles.
What happens to air inside a balloon when it is inflated?
The molecules of air inside of an inflated balloon are very far apart and moving rapidly. They collide with other molecules and with the inside surface of the balloon.
Gas particles move in a straight-line motion If the temperature of the air in the balloon increases the molecules move faster and have more collisions. The volume of the balloon increases as the molecules collide more frequently with its inside surface.
Why is the pressure inside a balloon the same as outside?
There are fewer air particles per unit of volume inside the balloon, but because those particles are moving faster, the inside and outside air pressure are the same.
How does air density affect pressure in a balloon?
If we change the conditions of the air inside the balloon, we can decrease density, while keeping air pressure the same. As we saw in the last section, the force of air pressure on an object depends on how often air particles collide with that object, as well as the force of each collision.
