Question

100ml water at 60°c is added to 200ml of water at 30°c.fibd the resultant temperature of mixture

Answer 1

Answer:

Mass of water ( m₂ ) = 200 ml = 0.2 kg. Temperature of water ( T₂ ) = 60°C = (273 + 60) K = 333 K. After mixing the two liquid ,heat loss by a liquid is heat gained by another liquid and they attain a common final temperature.
