Answer:

It will take 58 seconds

Step-by-step explanation:

If you have 1 kg of water in the jar, half of it will be 0.5 kg.

To vaporize half of the water (0.500 kg) the energy supply needed is

2297 kJ/kg*0.5kg=1148.5 kJ

If the stove is supplying 20 kJ/s, the time its needed is

\frac{1148.5 kJ}{20\frac{KJ}{s} }=57.425 s

It will last at least 58 seconds to vaporize half of the water.
