The answer is that the temperature a substance freezes is also its melting point.
Water freezes at 0 degrees Celsius into ice and if you heat ice up to 0 degrees Celsius it MELTS to give you water.
Evaporation is the change from liquid to gas and condensation is the change from gas to liquid (for water this happens at 100 degrees Celsius).

What happens to the temperature when a substance is melting?
For most substances, it's the same temperature. For example, ice melts at 0°C (273K), and water freezes also at 0°C. A few substances, such as agar, have a hysteresis. For example, agar melts at 85°C; to solidify it again, you have to cool it down to about 32-40°C.
What is the temperature at which water freezes on the Fahrenheit and Celsius sacels?
I
What is a good sentence for temperature?
Absolute Zero is the temperature at which everything - even atoms - freezes.
What is a measure of the average motion of the molecules in a substance?
When we heat a substance, the energy absorbed is converted into kinetic energy of the particles in it. The faster the particles in it vibrate, move, collide, etc. the higher the temperatureof a substance.So the expected answer is Temperature
What is a temperature scale in which water freezes at 32 degrees?
It is the Fahrenheit scale.
The temperature at which a substance freezes is lower than the temperature at which it melts?
Correct, the temperature at which a substance freezes is lower than the melting point.
The temperature at which a substance freezes is also its 1. Evaporation point 2. Melting point 3. Condensation point?
melting point...
What substance freezes at a temperature of 15 degrees c?
A suitable mixture of salt water.
How does fresh water freezes faster than salt water?
When water has a substance dissolved in it, it freezes at a lower temperature. Salt water has salt dissolved in the water, so it freezes at a lower temperature than fresh water.
What happens to the molecular motion of a liquid as it freezes?
As the temperature of a liquid substance lowers, the molecules and atoms making up the substance slow down their movement. The also pack closer together, making the substance more rigid, turning it into a solid.
What causes phase changes?
If a certain substance has reached a temperature at which it either melts, freezes, evaporates, ect.
Are the melting and freezing of a substance the same?
Yes. A substance melts and freezes at the same temperature. Melting is as it changes from solid to liquid, freezing is from liquid to solid.
The phase of matter can be changed by?
changing the temperature or surrounding pressure of a substance
32 in the T in D F at which W F?
32 is the temperature in degrees Fahrenheit there is also an expanded version of this which reads 32 is the T in D F at which W F 32 is the temperature in degrees Fahrenheit at which water freezes

Is 32 degrees Fahrenheit the temperature at which water freezes?
Yes, at this temperature the structure the atoms of water are orgainzed in changes, and the state of the substance changes.
What makes matter change from one phase to another?
I am pretty sure that it is the temperature which is applied to the substance. For example when heat is applied to a solid it melts, causing it to change from one phase to another. Also when a liquid freezes the temperature drops and it converts into a solid.
