Is there a difference between freezing point depression and freezing point?
This is simply because the evaporation enthalpy is bigger than the enthalpy of fusion. ΔTf = -Kf · m (m= molality) ΔTb = Kb · m (m= molality) what is important is that Kf is proportional to 1/Enthalpy of fusion and the sam is true for Kb (with enthalpy of evaporation)
When a substance changes from liquid to solid what is the energy?
The heat energy, or enthalpy, associated with a solid to liquid transition is the enthalpy of fusion and that associated with a solid to gas transition is the enthalpy of sublimation.
Are melting and freezing point of Platinum are same?
Yes the melting temperature and the freezing temperature of materials are the same.
What is the temperature that freezing occurs?
This is called the melting (or freezing) point
What is the coldest temperature past freezing point?
The coldest temperature below freezing point is -273 degrees centigrade

What is sub freezing temperature?
temperature below freezing point of water.
What temperature is the freezing temperature?
32 degrees Fahrenheit (or 0 degrees celsius) is the point of freezing.
When the temperature is 0 degrees Fahrenheit is it warmer or colder that the freezing temperature of water?
The freezing temperature of water is 0 degrees celsius or 32 degrees fahrenheit so it is colder than the freezing temperature of water.
What conditions are required for it to sleet?
ground temperature below freezing, and air temperature slightly above freezing.
Are melting and freezing point of Platinum are same?
Yes the melting temperature and the freezing temperature of materials are the same.
What are ideal conditions for freezing?
A temperature under the freezing point.
What is the freezing point of Hydrofluorosidic Acid?
Freezing Temperature for Fluoride
What is the temperature that freezing occurs?
This is called the melting (or freezing) point
How many degrees does water changes from a liquid state to a solid state at what degrees?
Freezing occurs without any change in temperature. A liquid at freezing temperature becomes a solid at freezing temperature.
When you are making ice cream do the changes of state is a release of heat or an absorption of heat?
Freezing is an exothermic phenomenon; the enthalpy of fsion is released.
