An experiment takes 10 minutes to raise the temperature of water in a container from 0°C to 100°C and another 55 minutes to convert it totally into steam by a heater supplying heat at a uniform rate. Neglecting the specific heat of the container and taking specific heat of water to be 1cal/g°C,the heat of vapourization according to this experiment will come out to be:

1)530cal/g

2)540cal/g

3)550cal/g

4)560cal/g
