Question

A bottle of water at room temperature was placed in a refrigerator at 5 [°C]. Assuming that room temperature is 82 [°F], and that the bottle of water reaches thermal equilibrium with the refrigerator, find the temperature change of the water in [°C], [°F], [K], and [R].

Answer 1

The temperature change is 22.8ºC = 72.8ºF = 295.8K = 532.5R

Step-by-step explanation:

The formulas used to convert the different temperatures are the following:

From ºF to ºC

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

From ºC to ºF

`F=(5)/(9)xC +32`

From ºC to K

`K=C+273.15`

From ºF to R

`R=F+459.67`

The initial temperature of the water is 82ºF = 27.8ºC and the final temperature is 5ºC. Thus, the temperature change is the difference between these two temperatures:

27.8ºC - 5ºC = 22.8ºC

Converting in all units the results are:

22.8ºC = 72.8ºF = 295.8K = 532.5R
