A measured temperature on Fahrenheit scale is `200^(@)F`. What will this reading be on clesius scale?

A

`40^(@)C`

B

`94^(@)C`

C

`93.3^(@)C`

D

`30^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
C

The are the common scale to measure temperature `""^(@)C` (degree Celsium) `""^(@) F` (degree Fahrenheit ) and K (kelvin) . The K is the SI unit.
The temperatures on two scales are related to each other by the following relationship.
`""^(@) F = (9)/(5)t^(@)C + 32`
Putting the values in above equation
` 200-32 = (9)/(5) t^(@)C rArr (9)/(5) t^(@)C = 168`
`rArr t^(@)C = (168 xx 5)/(9) = 93.3^(@)C`
