Answer:

I found that the water released #31,350J# of energy

Explanation:

We could use the fact that a mass #m# of water to change from temperature #T_i=25°C# to #T_f=10°C# will release energy #Q# given as:
#Q=mcDeltaT#

Where:

#c=4.18J/(g°C)# specific heat of water (i.e. the energy in Joules to change of #1°C# the mass of #1g# of water);

#DeltaT=T_f-T_i#

You get:

#Q=500*4.18(10-25)=-31,350J#

The minus sign indicates the loss of energy sustained by the water.

Hope it helps!
