OTHERMOCHEMISTRY Using specific heat capacity to find temperature change 84°F Sunny A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 5.20 kg of water at 33.7 °C. During the reaction 84.5 kJ of heat flows out of the flask and into the bath. Calculate the new temperature of the water bath. You can assume the specific heat capacity of water under these conditions is 4.18 J-g¹K -1 . answer to 3 significant digits.
