Question

1. Describe an experiment to show that gases do not have a fixed shape or volume.
​

Answer 1

Answer:

It is very easy to determine that gase do not have fixed shape and volume.

Take small amount of gas in a closed beaker and measure its volume.

Now Transfer the gas in to a big beaker and measure its volume.

You will see that the volume has changed which shows that gases do not have fixed volume.

We also observed that the gas changed its shape from small beaker to bigger one hence it does not have fixed shape.
