A rail way 50m long, with initial temperature of 20degree celsius subjected to a great heat. How much will it expand when its temperature is tripled?

  • Physics -

    I wonder what tripled means, 60C? Temperature is normally thought of in physics as average kinetic energy, and temperature is on an absolute scale.

    Tripling that is 951K

    My gut tells me that the author is trying to trick you, for some silly purpose.
