Answer:- 452.85 degree C and 847.13 degree F.
Solution:- The given temperature is 726 K and it asks to convert it to degree C and degree F. For degree C to K conversion we add 273.15. So, if we are doing opposite conversion that is K to degree C then we need to subtract 273.15.
degree C = 726 - 273.15 = 452.85
Now we could convert degree C to degree F using the formula:
[tex](C*\frac{9}{5})+32[/tex]
Let's plug in the value of degree C temperature in it:
[tex](452.85*\frac{9}{5})+32[/tex]
= 815.13 + 32
= 847.13 degree F
So, 726 K would be 452.85 degree C and 847.13 degree F.
