The correct option is A 108 ∘F,60 K
By using the formula,
C5=F−329
We find the relation between change in temperature in Celsius scale and Fahrenheit scale as ΔTF=95ΔTC .......(1)
From the data given in the question, change in temperature measured in Celsius scale is given by
ΔTC=90 ∘C−30 ∘C=60 ∘C .......(2)
Using (2) in (1),
ΔTF=95ΔTC=95(60 ∘C)=108 ∘F
Relation between Celsius and Kelvin scale is given by C=K−273
Using this, we find the relation between the change in temperature measured in Celsius scale and Kelvin scale as
ΔTK=ΔTC .......(3)
From (3), we can conclude that,
ΔTK=60 K
Hence, option (a) is the correct answer.
