TED-Ed: The ABC's of gas: Avogadro, Boyle, Charles - Brian Bennett

The video tutorial explains the fundamental gas laws: Boyle's Law, Charles' Law, and Avogadro's Law. Boyle's Law describes the inverse relationship between pressure and volume. Charles' Law explains the direct relationship between temperature and volume. Avogadro's Law states that the volume of gas increases with the number of gas particles. These laws help predict gas behavior under different conditions.

What happens to the pressure inside a container when its volume is decreased, according to Boyle's Law?

• The pressure decreases.

• The pressure fluctuates randomly.

• The pressure remains constant.

• The pressure increases.

Which of the following best describes the relationship between temperature and volume in Charles' Law?

• As temperature increases, volume remains constant.

• As temperature increases, volume decreases.

• As temperature increases, volume increases.

• Temperature and volume are unrelated.

What is the primary factor that causes a hot-air balloon to inflate?

• Cooling the air inside.

• Heating the air inside.

• Decreasing the air pressure inside.

• Adding more air particles.

According to Avogadro's Law, what happens to the volume of a gas when more gas particles are added to a container?

• The volume increases.

• The volume decreases.

• The volume remains the same.

• The volume fluctuates.

What is a common consequence of adding too many gas particles to a closed container?

• The container will change color.

• The container will shrink.

• The container will burst.

• The container will become heavier.
