Gas molecules collide with each other and the container walls, leading to pressure exerted by the gas. These collisions also affect the temperature, volume, and density of the gas. Additionally, the frequency and force of collisions determine properties such as diffusion and reaction rates.

What are gas molecules colliding with no change in total energy?
When gas molecules collide without a change in total energy, it means that the collisions are elastic. In an elastic collision, the kinetic energy of the gas molecules before and after the collision remains constant. This type of collision conserves energy and momentum.
How do molecules move from place to place?
Molecules move from place to place by diffusing, or spreading out, due to their kinetic energy. This movement is random, with molecules colliding and changing direction as they interact with their environment. Other factors such as temperature, pressure, and concentration gradients also influence the movement of molecules.
What is the motion for molecules?
The motion of molecules is random and chaotic, driven by thermal energy. Molecules vibrate, rotate, and translate in all directions, constantly colliding with each other and their surroundings. This motion is fundamental to processes such as diffusion and chemical reactions.
When a gas is compressed in a cylinder what does the distance between the gas molecules do?
The compression will result in a lowering in the average distance between molecules of the gas. Imagine that the cylinder is like that in an internal combustion engine, with a piston inside the cylinder. The compression is accomplished by pressing the gas into a reduced volume. The number of gas molecules remains the same. With the same number of molecules in a reduced volume, the gas molecules are pressed more closely together, lowering the average distance between the gas molecules.
What happens to the number of molecules of the gas when it is compressed?
When a gas is compressed, the volume it occupies decreases, causing the gas molecules to be closer together. The number of molecules remains the same, as no molecules are added or removed during compression.
What exactly is gas pressure?
Force of gas molecules colliding with the container
How do the particles move in gas?
the atoms and molecules are free to move independently, colliding frequently.
How do particles in a gas move?

Will decreasing the number of gas molecules increase the volume of a gas?
Decreasing the number of gas molecules typically decreases the volume of the gas, assuming pressure and temperature remain constant. This is because there are fewer molecules colliding with the container walls, reducing the pressure and allowing the gas to occupy a larger volume to maintain equilibrium.

What causes a pressure in a gas?
Heat. The addition of heat causes expansion and spreading of the molecules which in turn causes an increase in pressure.
A gas is a collection of what that move about freely?
A gas is a collection of molecules or atoms that move about freely in all directions. They have high kinetic energy and are continuously colliding with each other and the walls of their container, creating pressure.
What changes from which state of matter to which state?
Solid-molecules vibrate but are fixed in place. Liquid-molecules are free to move about, but still are attracted to each other. Gas-molecules move freely in any direction until colliding with another molecule.
What is a compressional wave caused by colliding air molecules?
Sound Waves
What happens to gas particles when air leaks out an inflated ball?
The gas molecules are constantly in motion, colliding with each other and the walls of the ball. The pressure inside the ball is also much greater than the pressure outside the ball. When there's a hole in the ball, the molecules keep colliding, and some make there way out through the hole. Remember that the molecules want to go to the area of lowest pressure so that they can be at equilibrium.
