Question

how will you show that air has pressure very short answer ... ​

Answer 1

Answer:

When air is pumped inside a balloon, it expands in size. This shows that the air inside exerts pressure on the walls of the balloon.

Answer 2

$\bf\huge{\underline{\boxed{\red{ANSWER}}}}$

Ping-Pong Funnel. Put a ping-pong ball inside the wide part of a funnel and blow hard into the narrow end. Why doesn’t the ball pop out? As you blow into the funnel, the air moves faster and lowers the air pressure underneath the ball. Because the air pressure is higher above the ball than below it, the ball is pushed down into the funnel—no matter how hard you blow or which direction you point the funnel.
