Bridges. Bridges don't deal well with temperature changes. In order to combat this, engineers have come up with some workarounds that allow bridges to flex as they expand or contract. In this episode of Crash Course Physics, Shini talks to us about temperature and the ideal gas law. Also, we figure out how much air is in your car. -- Produced in collaboration with PBS Digital Studios: http://youtube.com/pbsdigitalstudios -- Want to find Crash Course elsewhere on the internet?
