A basketball player pumps air into a basketball until no more air can be pushed inside

• The particles leak outside of the ball, because of the amount of pressure in the ball.

• The particles smash, and crush because they are to close together

• The particles are farther apart, and will run away from each other.

• The particles inside the ball are closer together, and bounce into each other more than the particles outside the ball.

A student was wondering about what is inside a balloon that contain helium. Which of the following describes what is between the helium particles in the balloon?

• Particles

  Air

• Space,

  Nothing

• Matter

  Wind

A group of students put 5 mL of a white solid substance into a bottle. They poured 10 mL of a clear liquid into the bottle and quickly sealed the system with a stopper with a balloon on top. They swirled the liquid to mix the two substances together and set the closed bottle-balloon system on the table. The mixture bubbled at the bottom of the bottle and the balloon slowly began to inflate. Has a chemical reaction occurred?

What will happen to the particles inside the ball, if it rolls over a sharp object?

• Particles will rush into the ball until the pressure is equal inside and outside the ball

• Particles inside the ball will speed up because the pressure inside the ball decreases.

• Particles will rush out of the ball until the pressure is equal inside and outside the ball.

• Particles outside the ball will speed up as the pressure increases.
