Chemistry

Tempered glass is made by heating glass to a temperature to 620ºC, then cooling it quickly by spraying the surface in a procedureknown as quenching. Quenching cools the outer surfaces more quicklythan the center. As the center cools, it tries to pull back fromthe outer surfaces, which results in tension of the center andcompression of the surfaces, which gives tempered glass itsstrength. The specific heat capacity of glass is 0.84 J/g ºC. A23.6 kilogram windshield at 620ºC is tempered using 54.2 kg ofwater at 18.6ºC. If the windshield is removed when its temperatureis 75.3ºC, what is the new temperature of the water? Assume that nowater evaporates. Round your answer to the nearest 10th degree.(Type \"degrees\" for the units.)
