Question: Which Will Freeze Faster Hot Or Cold Water?

Does hot water freeze faster than cold water Mythbusters?

The Mpemba effect is a process in which hot water can freeze faster than cold water.

The phenomenon is temperature-dependent..

Is the mpemba effect real?

Under our definition of the Mpemba effect, akin to the definition in the ‘original’ paper by Mpemba & Osborne8 (in which they documented “the time for water to start freezing”) we are forced to conclude that the ‘Mpemba effect’ is not a genuine physical effect and is a scientific fallacy.

Does hot water freeze faster in the freezer?

Hot water can in fact freeze faster than cold water for a wide range of experimental conditions. This phenomenon is extremely counterintuitive, and surprising even to most scientists, but it is in fact real. … The phenomenon that hot water may freeze faster than cold is often called the Mpemba effect.

What liquid freezes the fastest?

WaterWater did freeze the fastest with an average of 56.6 minutes.

Does salt water freeze faster?

Salt water freezes at a lower temperature than the 32 degrees F at which freshwater freezes. The difference between the air temperature and the freezing point of salt water is bigger than the difference between the air temperature and the freezing point of freshwater. This makes the ice with salt on it melt faster.

Does hot water kill germs?

Hot water kills germs, though it has to be very hot According to WHO, temperatures of 140°F to 150°F are enough to kill most viruses, and boiling water makes it safe from pathogens like bacteria, viruses, and protozoa.

Should I boil hot or cold water?

Cold water boils faster than hot water. There is, however, a good reason to use cold water instead of hot for cooking: hot water will contain more dissolved minerals from your pipes, which can give your food an off-flavor, particularly if you reduce the water a lot.

What temp is freezing rain?

Freezing rain is simply rain that falls through a shallow layer of cold temperatures at or below 0 degrees Celsius (32 degrees F) near the surface.

Does cold water heat up faster?

“Cold water does not boil faster than hot water. … As a result, cold water will be absorbing heat faster while it is still cold; once it gets up to the temperature of hot water, the heating rate slows down and from there it takes just as long to bring it to a boil as the water that was hot to begin with.

Is it faster to make ice with hot water?

No worries, try this trick for ice cubes that freeze quickly: fill your ice tray with hot water and put it in the freezer. This phenomenon, called the Mpemba effect, may seem backwards, but actually works reliably well. You’ll get frozen ice cubes significantly faster by starting with hot water than cold.
