Question

MODELING REAL LIFE The formula $K=C+273.15$ converts temperature from degree Celsius C to Kelvin K.

(c) Convert 300 kelvin to degree Celsius.

Answer 1

Move the variable to the left hand side and change its sign

$300-C=273.15$

Move the constant to the right hand side and change its sign

$-C=273.15-300$

Calculate the difference

$$\begin{gathered} -C=273.15-300 \\ -C=-26.85 \end{gathered}$$

Change its sign

$C=26.85$
