q = mc theta

where,

Q = heat gained

m = mass of the substance = 670g

c = heat capacity of water = 4.1 J/g°C

theta = Change in temperature = (66-25.7)

Now put all the given values in the above formula, we get the amount of heat needed.

q = mctheta

q=670*4.1 * (66-25.7)

=670*4.1*40.3

=110704.1
