Q.3.83 - An Introduction to General, Organic, and Biological Chemistry

Question

 What is $-{15}^{\circ }\mathrm{F}$ in degrees Celsius and in kelvins? 

Step-by-Step Solution

Answer

$-26.1^{o}C and 246.9 K$

Step 1: Given Information

Temperature = $-{15}^{o}F$

Step 2: Explanation

using the formulas,

${}^{\circ }\mathrm{C}=\left({}^{\circ }\mathrm{F}-32\right)\times 5/9$

Temperature = $\frac{-15-32}{1.8}=-{26.1}^{\circ }\mathrm{C}$

$K=\left[\frac{F-32}{1.8}\right]+273$

$\left[\frac{-15-32}{1.8}\right]+273=246.9\mathrm{K}$
