Answer
a)20°C is higher than 20°F
b)100°C is higher than 180°F
c)60°C is higher than 100°F
d)20°F is higher than -12°C
Work Step by Step
It takes 180°F to cover the same temperature interval as 100°C.
The starting points of the two scales are different,so we cannot convert a temperature on one scale to a temperature on the other just multiplying by a unit factor
Having known that converting the Fahrenheit scale to Celsius scale we subtract 32°F to reach zero point on Celsius scale as shown below
_°C=1.0°C/1.8°F(x°F-32°F)
Using the above formula I converted the 20°F to °C and got -6.667°C hence the answer in (a)
For (b) 180°F is 82.22°C hence 100°C is higher
For (c) 60°C is higher since 100°F is equal to 37.7°C
For (d) 20°F is higher than -12°C since 20°F is equal to -6.6667°C
