Question

When 165 ml of water at 22°c is mixed with 85 ml of water at 82°c, what is the finaltemperature? (assume that no heatis lost to the surroundings; d of water is 1 .00 g/ml)

Answer 1

Answer:

let the final temp be X C.

m1 x c x ( X -22 ) = m2 x c x ( 82 - X )

165 c ( X-22 ) = 85 c ( 82 - X )

X = 42 C
