SUMMARY

The discussion clarifies the conversion of temperature changes from Celsius to Kelvin. It establishes that a temperature change of 75°C is equivalent to a change of 75K due to the equal magnitude of degree increments in both scales. The confusion arises from the misunderstanding that the actual temperature must be converted, while only the change in temperature is relevant. Therefore, the book's answer of 75K is correct.

PREREQUISITES
  • Understanding of temperature scales (Celsius and Kelvin)
  • Basic knowledge of thermal physics
  • Familiarity with temperature conversion principles
  • Ability to interpret scientific problems
NEXT STEPS
  • Study the principles of thermodynamics
  • Learn about temperature scale conversions in detail
  • Explore the concept of absolute zero and its significance
  • Investigate real-world applications of temperature changes in scientific experiments
USEFUL FOR

Students in physics or chemistry, educators teaching temperature concepts, and anyone needing clarity on temperature scale conversions.

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.
