Mythbusters: Underwater Car

What was the main scientific principle tested in the episode?

• Buoyancy

• Air pressure

• Newton's Third Law

• Thermal expansion

Why was it nearly impossible to open the car door immediately after submersion?

• The pressure outside was much higher than inside

• The water caused a vacuum inside the car

• The doors were locked automatically

• The car was not designed to be submerged

What happens to the air volume inside the car as it sinks deeper?

• It increases

• It remains the same

• It decreases

• It turns into a vacuum

What real-life safety advice did the MythBusters confirm from this experiment?

• You should always try to open the door first

• You should break the window as soon as possible

• You should wait for rescuers to arrive

• You should stay inside the car for as long as possible

What tool is recommended for breaking a car window in an emergency?

• Hammer

• Screwdriver

• A specialized window punch

Which law explains the behavior of gases under pressure?

• Newton's Law

• Boyle’s Law

• Charles's Law

What makes it easier to open the car door when it's fully submerged?

• Unequal pressure

• Equalized pressure

• No pressure

What should you do if you cannot open the car door underwater?

• Wait for help

• You should break the window as soon as possible

• Try to open the door again

Why is it easier to break the side window than the windshield?

• The windshield is made of laminated safety glass
  

• The windshield is thinner
  

• The windshield has more air pressure against it
  

• The windshield is weaker

  
  

In the experiment, what was the biggest initial obstacle to escaping the submerged car?

• Lack of oxygen

• Water pressure keeping the doors shut

• The seatbelt mechanism failing
  

• The windows being shatterproof
