Chemistry---how do gas molecules create pressure?

Question

how do they relate? also how does pressure relate temperature. and how does volume relate to temp. and how to volume relate to pressure?

Answer 1

Gas molecules are free-flowing atoms. They constantly bounce around, and if they are confined in one space, they bounce rapidly off of the walls of the container, therefore creating pressure. The higher the temperature, the faster the gas molecules move around, therefore increasing the pressure. As temperature increases, volume may also increase (depending on whether the container is flexible or not, like a balloon or a tire), because the gas molecules are firing at the walls of the container faster & expanding it. Volume relates to pressure in that the smaller the volume of the container, the higher the pressure. The bigger the container, the lower the pressure.

Answer 2

The pressure of a gas is a measure of how frequently molecules of the gas hit the sides of the container the gas is held in. So if there are a lot of gas molecules in a small container, there will be more pressure exerted because the molecues are bumping into each other.
In terms of temperature, if the temperature is high, the particles are moving faster and the kinetic energy will be greater. and so will the pressure because they are moving faster and bumping into each other.
Volume relates to pressure, because like I said before, if the volume is smaller, the pressure is higher because the molecules are closer together and hitting each other.
You can use the ideal gas law to relate things together as well. Ideal gas law : PV=nRT
P=pressure
V=volume
n=mols
R= constant .08206
T=temperature

I hope this helps!! :)

Answer 3

The gas laws are well known.

basically Pressure and Volume are inverse (more pressure = less volume)

Volume and temperature are direct (think of heating a balloon, the volume will get bigger)

Pressure and temperature are direct (think of heating up a propane tank. What will happen to the pressure in a rigid tank?)

Finally, pressure is created by the energy of the gas molecules striking the walls of the container they are held in.

Answer 4

Gas molecules create pressure by increase in their kinetic energy.
Temperature increases and pressure increases.
Temp decrease will reduce volume.
volume incres then pressure increases

Answer 5

gas expands so it like popping a bag what happenes while u start up twisting it it gets smaller however the gas is getting greater beneficial yet another excuse because of the fact while u have a gas in an air tight seal and start up off making it smaller witht he same quantity of gas the gas keeps to be a similar quantity however the seal subject gets smaller so it starts to presserizes and get to pressuerized growth!
