Exercise 3: Temperature Measurements

3. The temperature of a gas was measured as 234.5 K. What is this temperature in oC and oF?

ANSWER: -38.6oC and -37.5oF

 

Solution to Exercise 3: Temperature Measurements

First convert from K to oC:\(K\;=\;^oC\;+\;273.15\;\;and\;\;^oC\;=\;K\;-\;273.15\;=\;234.5\;K\;-\;273.15\;=\;\mathbf{-38.6\;^oC}\)

Next, convert -38.6oC to oF.

\(^oF\;=\;1.8\;^oC\;+\;32\;=\;-38.6\;^oC\;+\;32\;=\;\mathbf{-37.5\;^oF}\)
