Question

In El Paso, the temperature increases from 10◦C during the night to 32◦C during the day (a change of 22 C◦).

(a) What is the temperature change in Fahrenheit degrees? Is this value greater than, less than, or equal to the temperature change in Celcius degrees? Explain briefly.

(b) What is the temperature change in Kelvin degrees? Is this value greater than, less than, or equal to the temperature change in Celcius degrees? Explain briefly.

Answer 1

formula used:

if C is temperature in Celsius, F is temperature in farenheit,

then C/5=(F-32)/9

temperature in kelvin=273+C

part a:

given that C=22

==>(F-32)/9=22/5

==>F=9*(22/5)+32=71.6 degree farenheit

in terms of absolute value, F is higher than C.

but in terms of temperature value, both are same with only expressed in different units

part b:

temperature change in kelvin=temperature change in celcius

(as only the scale in kelvin is shifted by 273 , difference remains the same)

hence temperature change in kelvin is 22 K.
