Freezing time and freezing temperature of various liquids are among the most crucial physical properties of the liquid. This physical properties may adjust when other material are liquified in or combined with liquids. This job will uncover this subject using water and salt that room both for sure and easily accessible in many households. We will carry out some experiments and see which one freezes faster? water or Salt water?

You are watching: What freezes faster water or salt water
If you are new in doing scientific research project, click “How come Start” in the key page. There you will certainly find valuable links that define different types of scientific research projects, scientific method, variables, hypothesis, graph, abstract and all other general basics the you should know.
Find out around freezing suggest of different material. Check out books, magazines or ask professionals who might know in order to learn around the components that may impact freezing time and freezing temperature. Save track of wherein you obtained your info from.
As a part of info gathering we may want to execute some initial experiment to uncover out what happens during the freezing process of water. Simply place a cup that water v a thermometry on that inside the freezer and also check it’s problem every five minutes. Conditions that you examine are time, water temperature and water problem (frozen or not).
During this initial experiment you may make the notes choose this:
|Time||Water Temperature||Water status|
|10:00 a.m.||22º C (71º F)||Liquid|
|10:05 a.m.||17º C||Liquid|
|10:25 a.m.||5º C|
|10:30 a.m.||2.5º C|
|10:35 a.m.||0º C||Liquid|
|10:40 a.m.||0º C||Frozen|
|10:45 a.m.||-2º C||Frozen|
|10:50 a.m.||-4º C||Frozen|
C means Celsius or CentigradeF median Fahrenheit
The above experiment reflects that in around 35 minutes water temperature drops come 0º C and then water freezes and also in around 50 minutes the temperature the frozen water gets to -4ºC.
Also this experiment mirrors that the freeze temperature that distilled water the we supplied for our test is 0ºC.
What we find out from this experiment is the if the salt have the ability to increase the freezing temperature the water (from 0ºC to 5ºC for example) climate water will certainly freeze faster because it it s okay to that temperature in 25 minutes instead of 35 minutes. However if salt decreases the freezing temperature come a negative number such together -2º C, climate it will certainly take much more time because that water come freeze since it takes an ext time (about 45 minutes) to get to that temperature.
Remember that all these times relies on exactly how cold her freezer is. Her results could be different.
