Sir heavy water ka boiling point 121 degree Celsius nahi 101.4 degree Celsius hota hai aap jo bata rahe hai 121 degree Celsius wo pressure cooker me normal water ka Boling point hota hai because pressure cooker me 14.7 psi k jagha extra 15 psi ka pressure create hota hai Matalab lagbhag 30 psi so Boling point 121 degree Celsius chala jata hai .. I hope aap apna mistake sudhar lenge.. thank you 🙏
