·Hypothesis:Salt affects the time and temperature at which water freezes.· Materials:Plastic cups, measuring cup, water, salt, teaspoon, thermometer, marker, clock or watch, freezer· Steps:1. Put 100 ml of water in each cup. Use the thermometer to make sure that the water in both cups...
The Mpemba effect is the name given to the assertion that it is quicker to cool water to a given temperature when the initial temperature is higher. This assertion seems counter-intuitive and yet references to the effect go back at least to the writings of Aristotle. Indeed, at first thought...

As you probably know, the freezing point of water is 32°F (0°C). But did you know that the temperature of your freezer can affect how well it freezes food? If your freezer is too cold, your food will freeze too hard and you’ll end up with ice crystals. If your freezer is too...

Erasto Mpemba noted that when his class was making ice cream, he placed a near-boiling blend of sugar and milk (which is mostly water) into a freezer, and it froze before other mixtures which had been cooled to room temperature before freezin...
ΔTf=Kf×m=5.12°C/m×0.862mol/kg≈4.41°C 6. Calculate the Freezing Point of the Solution: Tsolutionf=Tbenzenef−ΔTf=5.5°C−4.41°C≈1.09°C Final Answer:The temperature at which the solution freezes is approximately 1.09 °C. Show More ...
Water freezes at thirty-two degrees Fahrenheit.水在华氏三十二度时结冰.Water boils at one hundred degrees centigrade.水在摄氏一百度时沸腾.这里的单位词在人们都很清楚是什么度量制度时,可以省略.You are 37℃.(读作 thirty-seven degrees)你是三十七度.(摄氏)It\'s seven degrees below zero.今天是零下七...
