Given a liter of water just at boiling, how much energy does it take to boil it all?

Solutions

Expert Solution

Since the water is at boiling temperature, then the energy is only needed for the phase change of water from liquid to gas.

The energy needed for the phase change can be calculated as

Where m is mass of the water, and L is latent heat of vapourization.

For water L = 2.26 x 10⁶ J/kg

So, for the given problem, the required energy is
