Answer on Molecular Physics | Thermodynamics Question for Rooky

Question #1478
If 200g of water at 20 degrees Celsius is combined with 100g of water at 80 degrees Celsius, what is the final temperature of the 200g of water?
Expert's answer
The final temperature of the 200g of water would be equal to the final temperature of the whole (200+100) mixture:
According to the heat balance equation,
Cm1Δ T1 = Cm2Δ T2
Δ T1 = (T-20)
Δ T2 = (80-T)
200*(T-20) = 100* (80 - T)
2T-40 = 80 - T
3T = 120
T = 40 C.
