Question

if you metal piece is heated from 40 degree Celsius to the 90 degrees celsius is the ratio of change in temperature on fahrenheit scale and is Kelvin scale is​

Answer 1

The ratio of change in temperature on Fahrenheit scale is  108 °F  and on Kelvin scale is​ 60° K.

Explanation:

Temperature on Celsius scale:

ΔT(F) = T°C x 9 / 5 +32

ΔT(F)  = ΔT°C x 9 / 5

ΔT°C  = 90 - 30 = 60°C

Temperature on Fahrenheit scale:

ΔT(F) = 60 x 9/5 = 108 °F

Temperature on kelvin scale:

T(K) = T°C + 273.15

ΔT(K) =  ΔT°C

ΔT(K) = 60° K

The ratio of change in temperature on Fahrenheit scale is  108 °F  and on Kelvin scale is​ 60° K.
