Tempered glass is made by heating glass to a temperature to 620 ºC, then cooling it quickly by spraying the surface in a procedure known as quenching. Quenching cools the outer surfaces more quickly than the center. As the center cools, it tries to pull back from the outer surfaces, which results in tension of the center and compression of the surfaces, which gives tempered glass its strength. The specific heat capacity of glass is 0.84 J/g ºC. A 23.6 kilogram windshield at 620ºC is tempered using 54.2 kg of water at 18.6ºC. If the windshield is removed when its temperature is 75.3ºC, what is the new temperature of the water? Assume that no water evaporates. Round your answer to the nearest 10th degree. (Type "degrees" for the units.)

Expert Solution

The new temperature of the water will be 66°C.

The detail calculation is shown below.

Several students were interested in using tempered glass as an additive for a portion of the fine aggregate in a Concrete Mix Design. They stated tempered glass has a high compressive strength and is an available resource. Their Control mix was to be 5 pounds of Coarse Aggregate, 5 pounds of Fine Aggregate, 2.5 pounds of cement, and 1.2 pounds of water. Their research idea was to use 5 pounds of Coarse Aggregate, 2.5 pounds of Fine Aggregate, 2.5 pounds...
