Officials fired water at the Third Avenue Bridge, which connects the Bronx and Manhattan, to cool it down.

Third Avenue Bridge, which connects New York’s the Bronx to Manhattan, got stuck in an open position due to the high heat on Monday.

FDNY officers arrived in boats and fired water at the structure to try and cool down the metal, which expanded after high temperatures in the city, officials say.

The incident caused major traffic delays during one of the hottest days of the year in New York but reopened on the same day.

    Because metals have way better thermal conductivity, they aren’t good at retaining heat.

    Heating equal masses of steel and water the same amount takes exactly the same energy, it just might take longer for the insulator vs. the conductor.

      Specific heat of liquid water is around 4. Steel is like .45-.50 or around there. So it would take 450-500 joules to increase 1kg of steel 1C. Would take around 4k joules to increase 1kg of water by 1C.
