Homework Help: Can someone explain? (Celcius to Kelvin question)

  1. Aug 29, 2011 #1
    A sample of liquid is heated from room temperature to just below the boiling point. The overall change in temperature is 75°C. Express this temperature change in kelvins.

    The book has the answer as 75K. How did they arrive at that answer? I don't think I understand the problem. I rather converted from 75C to K and got 348 instead. Help please?

    The change in temperature is 75 C, but the actual temperature is unknown. Since kelvin degrees and celsius degrees are the same magnitude, a change in temp. of 75 C is the same as a change of 75 K.
