all directions

Explanation:

mark me as brainliest

Answer 2

Explanation:-;

• When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces. ... This increases the pressure. Sometimes the pressure gets so great that the container bursts. This is why balloons and tyyres burst if you blow them up too much.
• Blowing up a balloon requires forcing additional air particles from our lungs into the balloon. These particles bumped the balloon's inside walls, creating enough air pressure to force the rubber of the balloon to expand and the balloon to inflate.

1. The pressure exerted by air on all bodies at all times in all directions is called air ... The air inside a balloon exerts pressure in all directions, and makes it blow up
