Gas Laws #3

Imagine you have a bicycle pump filled with air. What happens to the pressure inside the pump when you push the handle down, decreasing the volume of air inside, assuming the temperature and number of air particles remain constant?

• The pressure decreases

• The pressure remains the same

• The pressure increases

• The volume has no effect on pressure

Imagine a hot air balloon is being heated while it's tied down so it cannot rise and the amount of air inside remains the same. What happens to the volume of the air inside the balloon?

• The volume increases

• The volume decreases

• The volume remains unchanged

• The temperature has no effect on volume

Imagine you're inflating a balloon on a hot summer day. If the amount of air and the size of the balloon stay the same, what happens to the pressure inside the balloon as the temperature outside increases?

• Pressure inside the balloon decreases as the outside temperature increases

• Pressure inside the balloon is inversely proportional to the outside temperature

• Pressure inside the balloon is directly proportional to the outside temperature

• Pressure inside the balloon and the outside temperature are unrelated

Imagine you have a balloon filled with helium. If you add more helium to the balloon, keeping the temperature and the pressure constant, how does the volume of the balloon change?

• Adding more helium has no effect on the volume of the balloon

• The volume of the balloon remains the same

• The volume of the balloon increases

• The volume of the balloon decreases

What effect does increasing pressure have on a scuba diving tank's air if temperature and volume of the tank are kept constant?

• No effect on the tank's air

• Tank's air volume increases

• Tank's air becomes denser

• Tank's air becomes less dense

Imagine you have a balloon filled with air. What happens to the pressure inside the balloon if you gently increase its volume by blowing more air into it, keeping the temperature constant?

• Volume has no effect on pressure

• Pressure remains the same

• Pressure decreases

• Pressure increases

Imagine a balloon filled with air on a hot summer day. If the temperature around the balloon increases while keeping the balloon's size and shape constant, what happens to the motion of air molecules inside the balloon?

• No change in motion

• Molecules move slower

• Molecules stop moving

• Molecules move faster

Imagine you have a sealed balloon filled with helium gas at a beach party on a sunny day. If some helium atoms escape the balloon while the temperature and pressure outside the balloon remain constant, what happens to the balloon's size?

• Pressure inside the balloon increases

• No change in the balloon's size

• The balloon's size decreases

• The balloon's size increases

Imagine you have a container filled with gas. If the temperature of the gas is increased while keeping the volume of the container constant, what happens to the pressure of the gas inside?

• The pressure of the gas decreases

• The pressure of the gas remains the same

• The pressure of the gas increases

• The temperature has no effect on the gas pressure

Imagine you have a syringe filled with air, with the nozzle closed. If you pull the plunger back, increasing the volume inside the syringe while keeping the temperature constant, what happens to the pressure of the air inside?

• The pressure of the air increases

• The pressure of the air remains the same

• The pressure of the air decreases

• The volume has no effect on air pressure
