Question

You add 500 mL of water at 10°C to 100 mL of water at 70°C. What is the

most likely final temperature of the mixture?
O A. 80°C
OB. 10-C
OC. 20°C
O D. 60°C

Answer 1

Option (c) : 20°C

Step-by-step explanation:

`t(final) = (w1 * t1 + w2 * t2)/(w1 + w2)`

T(final) = 500* 10 + 100*70/600 = 20°C
