Relative temperatures during freezing of Water

In summary, the freezing point of water is 0 degrees Celsius or 32 degrees Fahrenheit at sea level. This is when water transitions from its liquid form to its solid form. Water freezes at 0 degrees Celsius because at this temperature, the molecules in water slow down enough to form a crystalline structure and bond together, creating ice. Water cannot freeze at temperatures above 0 degrees Celsius and the freezing point of water changes at higher altitudes as the atmospheric pressure decreases. The temperature directly affects the freezing process of water, with lower temperatures causing water to freeze and higher temperatures causing it to melt.

Hi I was wondering if anyone could help me out with this question?

You place 100ml of water into a freezer and monitor the variation of the temperature of the water with time.
After some time you find that the temperature reaches 0ºC, then remains constant at 0ºC for a period of time before continuing to fall.

What happens to the water during the period in which the temperature is constant?

Thnx,

Josh

At 0 degree C, water has to loose its latent heat for the phase transformation, that is why temperature remains constant for some time at 0 deg. C.
 

1. What is the freezing point of water?

The freezing point of water is 0 degrees Celsius or 32 degrees Fahrenheit at sea level. This is when water transitions from its liquid form to its solid form.

2. Why does water freeze at 0 degrees Celsius?

Water freezes at 0 degrees Celsius because at this temperature, the molecules in water slow down enough to form a crystalline structure and bond together, creating ice.

3. Can water freeze at temperatures above 0 degrees Celsius?

No, water cannot freeze at temperatures above 0 degrees Celsius. In order for water to freeze, it needs to reach 0 degrees Celsius or below.

4. Does the freezing point of water change at higher altitudes?

Yes, the freezing point of water changes at higher altitudes. As altitude increases, the atmospheric pressure decreases, causing the boiling point of water to decrease as well. This means that water freezes at a lower temperature at higher altitudes.

5. How does the temperature affect the freezing process of water?

The temperature directly affects the freezing process of water. As the temperature decreases, the molecules in water slow down and form bonds, causing the water to freeze. Conversely, as the temperature increases, the molecules move faster and the bonds between them weaken, causing the water to melt.
