  • Boiling Liquid Nitrogen

    This solution shows step-by-step calculations to determine the mass of nitrogen boils off when the coil cools down using the variables: heat lost by silver coin, specific latent heat of vaporisation, mass of nitrogen, and heat absorbed by nitrogen.

  • Heat

    As the silver coin at 90 degrees C is dropped in liquid nitrogen, the coin loses heat to the liquid nitrogen and cools down. The heat taken by the nitrogen from the coin goes to convert some of the liquid nitrogen into vapor.
