You begin with an object at a certain temperature,and you increase its temperature by an amount ∆T.For which one of the following values of ∆T will the final temperature of the object be LOWEST?
A) ∆T = 10 Kelvins
B) ∆T = 10 degrees Celsius
C) ∆T = 10 degrees Fahrenheit
D) Answers A, B, and C give the same final temperature.

The final temperature of the object will be lowest when the increase in temperature is in degrees Fahrenheit because Fahrenheit has a smaller degree size than both Celsius and Kelvin. Therefore, a change of 10 degrees Fahrenheit is less than both a change of 10 degrees Celsius and a change of 10 Kelvins, resulting in a lower final temperature. Answers A and B are incorrect because they involve larger degree sizes and would result in a higher final temperature.
