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:
Q1. 27°C+273=300K
or
473-273=200°C
