How it's used
While 開水 is understood, Hong Kongers overwhelmingly prefer the term 滾水 when referring to boiled water. The term 滾水 is used regardless of whether the water is currently hot or has cooled down to room temperature. Using 開水 can sometimes sound slightly more formal or influenced by Mandarin usage.
