Problem 11P

In order to take a nice warm bath, you mix 50 liters of hot water at 55°C with 25 liters of cold water at 10°C. How much new entropy have you created by mixing the water?

Step-by-Step Solution:

Step 1:

        To find the new entropy have you created by mixing the water

        Temperature of hot water TH = 55°C = 328 K

        Volume of Hot water VH = 50 L = 50 x 10-3 m3

        Temperature of cold water TC = 10°C = 283 K

        Volume of Cold water VC = 25 L = 25 x 10-3 m3

Step 2:

        Mass of Hot water mH = Vx Density of water

        mH  = 50x10-3 m3x 1000 Kg/m3

        mH  = 50 Kg

        Similarly

        Mass of Cold water mC = 25 Kg

Step 3:

Final temperature of the system

TF =

TF =

TF = 335 K
