Which statement would be the most useful for deriving the ideal gas law?
volume is directly proportional to the number of moles.
volume is inversely proportional to the temperature.
pressure is directly proportional to the volume.
pressure is inversely proportional to the number of moles.

Avogadros Law if pressure is the result of collision, molecules colliding with the wall of the container and every time they collide they exert a force. pressure is the result of the force and area. if we add more gas particles you are going to see more collisions with the wall of container the gas particles will exert a greater over the same exact area. they have a directly proportional relationship. Pressure and volume, pressure=force/area, if we have a container with the same number of particles but of different particles, the smaller volume containers will have smaller area and more collision increasing pressure so they have an inversely proportional relationship. Pressure and temperature, pressure=Force/area force is going to change not the area, when we heat up the molecules up they end up moving faster colliding with the walls of the container more often exerting a greater force. now Volume and temperature, if we heat the gas particles, they move more rapidly gas expands!.

We can’t you if you only tell us that you have to show us what the answers are
