Answer 1

Answer:

Explanation:

To convert it into Celsius scale, use the formula

`(C)/(5)=(F-32)/(9)`

substituting F=-40, we get `(C)/(5)=(-40-32)/(9)`

`(C)/(5)=(-72)/(9)`

`(C)/(5)=-8`

`C=-40^(@)C`

Temperature in Kelvin scale is gien by

`T=C+273`

Substituting C=-40, we get

`T=-40+273`

`=233K`

Answer 2

Answer:

Q1. 27°C+273=300K

or

473-273=200°C
