The amount of heat energy needed to cause the rise in temperature of the water initially at 4 degreess Celsius is 13,794 J.

Heat required to raise the temperature of the water

The quantity of heat required to raise the temperature of the water is calculated as follows;

Q = mcΔθ

where;

  • m is mass of the water
  • c is heat capacity
  • Δθ is change in temperature

Q = 100 x 4.18 x (37 - 4)

Q = 13,794 J

Thus, the amount of heat energy needed to cause the rise in temperature of the water initially at 4 degreess Celsius is 13,794 J.
