A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 8.10kg of water at 33.9 degrees celsius . During the reaction 69.0kJ of heat flows out of the bath and into the flask. Calculate the new temperature of the water bath.

The new temperature of the water bath is

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat released by water =     (1kJ=1000J)

m= mass of water = 8.10 kg= 8100 g   (1kg=1000g)

c = specific heat capacity =

Initial temperature of the water = =

Final temperature of the water =  = ?

Change in temperature ,

Putting in the values, we get:

The new temperature of the water bath is
