A )
when it reach temperature of 150 degree

Where did you got this number from? Looks a little bit too high for me.

because as I know when 100 C the water will start boiling

sorry not 150 just 100 C

No, water definitely boils at more than 100 °C at 500 kPa. Question is - how much. The easiest approach is to look for boiling point tables.
