How much energy is required to boil 150g water?

25 degrees Celsius is 298 degrees Kelvin; 100 degrees Celsius, 373 degrees Kelvin. = 150 g x 4.184 J/g/K x (373 – 298) K = 47,070 J. Thus, 47,070 J are needed to increase the temperature of 150 g of water from 25 degrees C to its boiling point of 100 degrees C.

What happens to the temperature of water while it is boiling?

When boiling occurs, the more energetic molecules change to a gas, spread out, and form bubbles. … In addition, gas molecules leaving the liquid take away heat energy. Therefore the temperature of the liquid remains constant during boiling. For example, water will remain at 100ºC while boiling.
