Question

with the help of an experiment, prove that gases expand on heating? ​

Answer 1

Answer:

Take an empty flask and clamp the flask in an upside-down position over a beaker of water in such a way that the glass tube dips inside the beaker. ... Now allow the beaker to cool. As the air inside the flask contracts, the water rises up the tube. This proves that gas like air expands on heating and contracts on cooling.

Hope its helpful for you

if it is correct then please mark me as brainliest

Answer 2

Answer:

The air in the flask expands and moves out of the flask through the tube into the beaker containing water. Now allow the beaker to cool. As the air inside the flask contracts, the water rises up the tube. This proves that gas like air expands on heating and contracts on cooling.

ACTIVITY

 1  Take an empty flask and clamp the flask in an upside-down position over a beaker of water in such a way that the glass tube dips inside the beaker

 2  Now heat the flask at the top

 3  The air in the flask expands and moves out of the flask through the tube into the beaker containing water.

 4  Observe the bubbles of air in the water.

 5  Now allow the beaker to cool.

 6  As the air inside the flask contracts, the water rises up the tube.

 7  This proves that gas like air expands on heating and contracts on cooling.
