饮用水烧到70℃就能喝了。烧水时可以根据声响判断水温。早在总体水温达到沸点之前,容器边界层水温已超过“沸点”,出现所谓过冷沸腾而发响。我国东南沿海地区水烧到水响(两米外能听见连贯音响)已超过70℃,在西部高原则须烧到大响。 Drinking water to 70 ℃ can drink. Water temperature can be judged according to the sound of water. As early as the overall water temperature reached the boiling point, the container boundary layer water temperature has exceeded the “boiling point”, the so-called supercooling and boiling sound. China’s southeast coast of the water to the water rang (two meters can hear the coherent audio) has more than 70 ℃, in the western plateau you have to burn a big ring.
