Problem
In a controlled environment the air temperature is monitored on the Kelvin scale. a. (i) When the thermometer shows , express this temperature in (a) degrees Celsius and (b) degrees Fahrenheit. b. (ii) Later the temperature drops by . Determine the final temperature in (a) Kelvin and (b) Fahrenheit.Intuitive explanation
Temperature scales are just different ways to label the same physical reality—molecular motion. The Kelvin scale is special because it starts at absolute zero (where all molecular motion stops), making it the natural choice for physics equations. When a problem gives you temperature in Kelvin, you can use it directly in formulas without conversion, and ratios of temperatures become physically meaningful.
