Heat required to raise the temperature of water is given as
[tex]Q = ms\Delta T[/tex]
here we know that
[tex]m = mass = 200 mL = 0.200 kg[/tex]
initial temperature = 15 degree C
final temperature = 40 degree C
specific heat capacity = 4186 J/kg C
now by the above formula we will have
[tex]Q = 0.200 (4186) (40 - 15) = 20930 J[/tex]
