A simple experiment to show that gases expand on heating is:
Attach a balloon to an empty plastic bottle. We can observe that the balloon is deflated.
Place the bottle in a heating water bath, we can observe that the balloon is expanding.
This is due to the expansion of air molecules and water vapor in the bottle due to heating which then fills the balloon.
Thus, gases expand on heating.
