Apostulate of the kinetic molecular theory is listed.

postulate: gas particles are extremely small and are far apart.

which of the following activities can be used to demonstrate the postulate? (1 point)

recording the change in pressure when heating an inflated tire

observing the ease of pushing the plunger of a capped nozzle syringe containing gas

observing colored gas spreading into an inverted jar placed on top of a jar containing the gas

recording the speed at which moth balls kept at the bottommost shelf of the closet can be smelled in the entire closet

Postulate: Gas particles are extremely small and are far apart.

The activities can be used to demonstrate the postulate is :

Observing colored gas spreading into an inverted jar placed on top of a jar containing the gas

Explanation:

colored gas spreading into an inverted jar placed on top of a jar containing the gas:

This occur because of two reasons:

1. The Gaseous particles are largely spaced . There is large distance between the gases molecule

2. The gases are in continuous motion . Hence they posses very high kinetic energy . This is the reason they mixes quickly if placed in a jar.

This occur by the process of diffusion.

Diffusion of Gases: The intermixing of particles from the region of high concentration to low concentration.

The coloured gas goes into the space between the gaseous molecule present in the jar.(Gases are far apart)

As soon as the coloured gas is mixed in the jar , It spread quickly by diffusion because , The gaseous particles are extremely small and are far apart.
