A little boy is playing with a plastic water bottle. He blows air into the bottle to make a whistling sound. Then, he wedges a plastic ball into the bottle to make a rattle. But the ball is too big—it gets stuck in the mouth of the bottle! The little boy panics and runs to his big brother for help.
Luckily, his older brother just studied the principle of Boyle's law. Based on what he learned, how will he get the ball out of the bottle?
by placing the bottle in the freezer to decrease the mass of the air inside the bottle
by pushing down on the bottle to decrease the temperature of the air in the bottle
by placing the bottle in the freezer to increase the air pressure inside the bottle
by pushing down on the bottle to increase the air pressure inside the bottle
