The normal boiling point of water is 100 o C because this is the temperature at which the vapor pressure of water is 760 mmHg, or 1 atm. Under normal conditions, when the pressure of the atmosphere is approximately 760 mmHg, water boils at 100 o C. At 10,000 feet above sea level, the pressure of the atmosphere is only 526 mmHg.

Freezing-point depression. Freezing point depression is responsible for keeping ice cream soft below 0°C.

[count] : the temperature at which a liquid freezes. The freezing point of water is 0 degrees Celsius and 32 degrees Fahrenheit. FREEZING POINT meaning: the temperature at which a liquid freezes., May 3, 2023 · When water freezes and ice crystals form there is actually a small amount of heat produced. The temperature of the water remains at 32°F as the ice crystals grow, and then a rapid temperature drop occurs as the ice crystals cool. Because foods are a complex mixture of many substances, their freezing point is below the freezing point of water. , The effect of freezing point depression is generally larger than that of boiling point elevation as values of K f are typically larger than those of K b. They range from around 1.5 to as much as 40 °C molal-1. For water, K b = 1.8 °C molal-1. So a 1 M NaCl solution should freeze at -3.6 °C. (i=2 since there are two ions) sFor water 1 M = 1m., Freezing point - the temperature at which a liquid turns into a solid.
