Heat and Thermal ExpansionHard

Question

If  HC, HK and HF are heat required to rise the temperature of one gram of water by one degree in Celsius, Kelvin and Fahrenheit temperature scales respectively then :-

Options

A.HK > HC > HF
B.HF > HC > HK
C.HK = HC > HF
D.HK = HC = HF

Solution

HC = msᐃθ = ms(1) oC
HK = msᐃθ = ms(1)K = ms(1)oC
HF = ms = msᐃθ(1oF) = ms(5/9)oC
∴ HC = HK > HF.
