The temperature of 2.0 kg of water is 100.0 degrees C, however the water is not boiling, because the external pressure acting on the water surface is 3.0 x 10^5 Pa. Usually, the boiling point of water at 3.0 x 10^5 Pa is 134 degrees C. Decide the amount of heat that must be added to the water to bring it to the point where it now begins to boil.
A. 2.8 × 10^5 J
B. 4.6 × 10^5 J
C. 7.9 × 10^5 J
D. 1.1 × 10^6 J
E. This cannot be determined from the information given.
