Question

Which of the following temperatures is the highest ?

• A. $100\, K$
• B. $-13^{\circ} F$
• C. $-20^{\circ} C$
• D. $-23^{\circ} C$

Answer 1

Answer: (C)

We convert all to ${ }^{\circ} C$ so we have
$100\, K=-173^{\circ} C$
and $-13^{\circ} F =\frac{9}{5} T_{C}+32$
$-13^{\circ} F =-25^{\circ} C$
$\Rightarrow -13^{\circ} F =-25^{\circ} C$
Thus $( C )-20^{\circ} C$ is the highest.
