A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The 1 atm pressure piston cylinder is also submerged in a large insulated water bath. (See sketch at right.) cylinder The temperature of the water bath is monitored, and it is determined from this data that 116. kJ of heat flows out of the water ba system during the reaction.

You apply 12,436 J of heat to a 132.6 g piece of ceramic. By how much does the temperature of ceramic increase (in other words, what is ΔT)? Assume a heat capacity of 1.325 J/g°C. Please show work
An insulated container is used to hold 46.2 g of water at 32.5 \deg C. A sample of copper weighing 14.2 g is placed in a dry test tube and heated for 30 minutes in a boiling water bath at 100.0\deg C. The heated test tube is carefully removed from the water bath with laboratory tongs and inclined so that the copper slides into the water in the insulated container. Given that the specific heat of solid copper is 0.385 J/(g-\deg C), calculate the maximum temperature of the water in the insulated container after the copper metal is added.
