Question
Which represents a greater temperature rise,$ 20^0C$ or $20^0 F?$
✓
Answer
$ F =\frac{9}{5} C +32$
$=\frac{9}{5} \times 20+32=68^{\circ} F$
$\Rightarrow 20^{\circ} C =68^{\circ} F$
$68^{\circ} F >20^{\circ} F$
$\text { or, } 20^{\circ} C >20^{\circ} F $
$20^{\circ} C$ represents a greater temperature rise.
