Answer on Other Physics Question for Tri
In a chemistry laboratory, a teaching assistant wants to prepare 500 ml of diluted acid solution. WDen acid
contacts with water, it will release lots of heat and vapor. Calculate the heat release from the acid after
making the diluted acid solution. Assume that, to make 500 ml of the wanted solution, he needs 550 ml of
distilled water mixed with a negligible amount of concentrated acid. The initial temperature of the water is
25° c, the latent heat of water evaporating is 2.3×106 J/kg, the specific heat of water is C-4.19 kJ. kg-I. K-1
and 1 ml ofthe solution is approximately 1 g.
