Change of Temp. converting from C to K in Entropy Change Problem

Postby Henry Krasner 1C » Mon Feb 04, 2019 3:56 pm

Why in an entropy change problem when converting to Kelvin does the book give two different values. It should be 37.6 C to 310.6 K and 157.9 C to 430.9 K. However the solutions manual states that its 310.8 K and 431 K respectively. Is this just a mistake on the book's part or is there a reason we change the temperature?
This is 4F.7 in the textbook for those who want reference.

Please delineate the problem itself so Chem Community users don't have to reference the book.

The conversion from Celsius to Kelvin is [K] = [C] + 273.15. So, 37.6ºC would be 310.75 or approx. 310.8ºK. Likewise, 157.9ºC is 431.05 or approx. 431.1ºK.
