Answer :
(a) The temperature in degree Celsius is,

(b) The temperature in Kelvin and in degree Fahrenheit is, 298K and
respectively.
(c) The temperature in degree Celsius and Kelvin is,
and 477.4 K respectively.
(d) The temperature in degree Fahrenheit and Celsius is,
and
respectively.
Explanation :
The conversion used for the temperature from Fahrenheit to degree Celsius is:

where,
= temperature in Fahrenheit
= temperature in centigrade
The conversion used for the temperature from degree Celsius to Kelvin is:

where,
= temperature in Kelvin
= temperature in centigrade
(a) As we are given the temperature in Fahrenheit is,

Now we have to determine the temperature in degree Celsius.



(b) As we are given the temperature in degree Celsius is,

Now we have to determine the temperature in Kelvin.



Now we have to determine the temperature in degree Fahrenheit.



(c) As we are given the temperature in Fahrenheit is,

Now we have to determine the temperature in degree Celsius.



Now we have to determine the temperature in Kelvin.



(d) As we are given the temperature in Kelvin, 77 K
Now we have to determine the temperature in degree Celsius.



Now we have to determine the temperature in degree Fahrenheit.
