Question

the temperature of a body rises from 90 degree celsius to 100 degree selsius

what is the rise in temperature in

1} degree fahrenheit

2} kelvin

Answer 1

Since, T_f = 32+ 9/5 T_c
where, T_f is the temperature in degree fahrenheit and T_c is the temperature in degree celsius.
Using conversion formula, we get 90⁰C = 194⁰F
and 100⁰C = 212⁰F

Hence,

rise in temperature in degree fahrenheit = (212 - 194)⁰F = 18⁰F

Since, T_c = T_k - 273.15
where T_k is the temperature in kelvin
Hence, using conversion formula, we get 90⁰C = 363.15 K and 100⁰C = 373.15 K
hence, rise in temperature in kelvin = (373.15​ - 273.15​) = 100 K
