What would freeze first?

What would freeze first?

One way [described in Jearl Walker’s book The Flying Circus of Physics (Wiley, 1975)] depends on the fact that hot water evaporates faster, so that if you started with equal masses of hot and cold water, there would soon be less of the hot water to freeze, and hence it would overtake the cold water and freeze first.

What would freeze first hot water or cold water?

Hot water freezes faster than cold, known as the Mpemba effect. Determining whether or not hot water can freeze faster than cold water may seem like a no-brainer. After all, water freezes at 0 degrees Celsius.

Which freezes first water or vinegar?

By adding acid to water, it gets harder for water molecules to bind and form ice. Thus, you need a lower freezing point to freeze vinegar than water.

Does ice freeze from top to bottom?

Water freezes from the top down—which allows ice to float—because of a strange quirk in how water’s density behaves at falling temperatures. For most compounds, falling temperatures cause the compound’s volume to decrease while its density increases—with the atoms and molecules becoming more tightly packed together.

Which one freezes in winter answers?

Answer: Ocean water freezes just like freshwater, but at lower temperatures. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. …

Why does hot water freeze first?

Evaporation. One explanation of the effect is that as the hot water cools, it loses mass to evaporation. With less mass, the liquid has to lose less heat to cool, and so it cools faster. With this explanation, the hot water freezes first, but only because there’s less of it to freeze.

Can hydrogen peroxide freeze?

No, hydrogen peroxide does not freeze it is impossible since H2O2 won’t harden even at -52 C.

What part of a lake freezes first?

shoreline
Freezing first occurs along the shoreline, where the water is shallow. Before ice can form on the surface, the entire water column must first reach 40 F, which is likely to first occur along the shoreline.
