How can water be below 32 degrees and still not be frozen?
Water can exist in a supercooled state below its freezing point of 32 degrees Fahrenheit, but it remains liquid because it lacks impurities or nucleation sites to initiate crystallization. When disturbed or seeded with an impurity, the supercooled water can rapidly freeze into solid ice.
What do lower the freezing point mean?
Lowering the freezing point simply means that you have done something to whatever you want to freeze (or don't want to freeze), so that a lower temperature is needed to make it freeze. For instance, adding salt to water lowers it's freezing point (which is normally 32 degrees Fahrenheit). That's why salting a sidewalk or roadway makes the ice melt under normal winter conditions. You can also lower the freezing point of water by adding alcohol or propylene glycol (automotive antifreeze).
What temperature is the freezing temperature outside?
32 F, 0 C, 273.15 Kelvin. At STP, pure water freezes at the above temperatures. Note that adding some solute (such as table salt or ethanol) will lower the freezing point (see Freezing Point Depression).
What would the final freezing point of water be if 3 mol of sugar were added to 1 kg of water?
-5.58 C

What do scientists try to produce by adding freezing nuclei to supercooled cloud s?
Scientists add freezing nuclei to supercooled clouds to induce precipitation through a process called cloud seeding. By introducing these nuclei, which can be ice crystals or other particles, they promote the formation of larger ice particles that eventually fall as snow or rain. This technique can enhance rainfall in drought-affected areas or improve snowfall for ski resorts. Overall, cloud seeding aims to manipulate weather patterns to benefit agricultural and water resource management.
How can water be below 32 degrees and still not be frozen?
Water can exist in a supercooled state below its freezing point of 32 degrees Fahrenheit, but it remains liquid because it lacks impurities or nucleation sites to initiate crystallization. When disturbed or seeded with an impurity, the supercooled water can rapidly freeze into solid ice.
What does adding antifreeze to water do?
It lowers the freezing point.
The freezing point of water can be lowered by adding?
By adding any "foreign" molecules or ions. Such as if u add sugar or salt to water, it will lower the freezing point of water.
What is the effect of adding p nitrotoluene to the freezing point of naphthalene?
Adding p-nitrotoluene to naphthalene will lower the freezing point of the mixture. This is due to the phenomenon of freezing point depression, where the presence of a solute lowers the freezing point of the solvent. The greater the concentration of the solute in the solvent, the lower the freezing point will be.
Will adding vinegar to dog water help keep it from freezing?
Adding vinegar to your dog's water will not prevent it from freezing. To prevent dog water from freezing, consider using a heated water bowl or changing the water frequently to ensure it does not have a chance to freeze.
How can you prevent water from freezing?
You can prevent water from freezing by adding substances like salt or antifreeze to lower the freezing point, insulating the water container, or keeping it in a heated area above freezing temperature.
Does adding vinegar to water affect its freezing time?
Yes because it is no longer water so will have a different freezing time or point
Scientists have been able to produce certain substances by adding the genetic information of one species to another Which term represents an organism that carries genetic information from more than o?
Transgenic
What effect does adding a solute have on the freezing point of a sloution?
Adding a solute to a solution lowers its freezing point, a phenomenon known as freezing point depression. This occurs because the solute particles interfere with the formation of the solid structure of the solvent, requiring a lower temperature to achieve freezing. The extent of this depression depends on the concentration of the solute and its properties, following colligative properties principles.
Why is salt not good for melting ice?
Adding a salt the freezing point of water decrease.
Why do you use salt on the icy roads?
Adding salt the freezing point of water is lowered.
