Freezing point of h2o
WebThe boiling point of water is 100 °C °C for the Celsius scale, and its unit is the degree Celsius (°C (°C). On the Fahrenheit scale, the freezing point of water is at 32 °F °F, and the boiling point is at 212 °F °F. The unit of temperature on this scale is the degree Fahrenheit (°F (°F). Note that the difference in degrees between the ... WebFreezing Point. The freezing point of water is zero degrees Centigrade or 32 degrees Fahrenheit. Rather, we can say that zero degrees are the point at which water is melting at the same rate it is freezing. Hence, creating a balance. Actually, at zero-degree water molecules are moving very slowly, and formation of solid begins i.e. Ice.
