Understanding Water Vapor and Air Particles in a Flask

What happens to the air particles in the flask as the water is heated and turns into vapor?

• They remain stationary.

• They are pushed out of the flask.

• They condense into liquid.

• They change color.

Why is the balloon placed on the flask after heating?

• To trap the air inside.

• To allow the water vapor to escape.

• To add more air into the flask.

• To seal the flask and observe vapor effects.

What causes the balloon to inflate slightly after being placed on the flask?

• The heat from the flask.

• The condensation of water vapor.

• The pressure from the water vapor.

• The expansion of air particles.

As the water vapor cools, what happens to the pressure inside the balloon?

• It increases significantly.

• It remains constant.

• It decreases, causing the balloon to expand.

• It causes the balloon to deflate completely.

Why does the balloon not reach the bottom of the flask?

• The flask is too small.

• There is still some air left inside the flask.

• The balloon is not elastic enough.

• The water vapor is too dense.
