How do you explain condensation?
Condensation is the process by which water vapor in the air is changed into liquid water. The phase change that accompanies water as it moves between its vapor, liquid, and solid form is exhibited in the arrangement of water molecules. Water molecules in the vapor form are arranged more randomly than in liquid water.
How does pressure affect condensation?
The higher the vapor pressure, the faster the rate of condensation. Condensation occurs when a water vapor molecule collides with a liquid water surface, and chemically binds to liquid water molecules. It is very important to understand that the higher the air temperature, the higher the saturation vapor pressure.
What is freeze point?
Freezing point, temperature at which a liquid becomes a solid. As with the melting point, increased pressure usually raises the freezing point. The freezing point is lower than the melting point in the case of mixtures and for certain organic compounds such as fats.
Which liquid has freezing point?
Common fluids and their freezing and melting points
| Fluid | Freezing and Melting Point (K) |
|---|---|
| Acetone | 179 |
| Alcohol, allyl | 144 |
| Alcohol, ethyl (ethanol) | 158.6 |
| Alcohol, isobutyl | 165 |
Do all liquids freeze at 32 degrees?
We’ve all been taught that water freezes at 32 degrees Fahrenheit, 0 degrees Celsius, 273.15 Kelvin. That’s not always the case, though. Scientists have found liquid water as cold as -40 degrees F in clouds and even cooled water down to -42 degrees F in the lab.
Is the freezing point the same for all liquids?
Almost everything has a unique temperature at which it will freeze/melt and condense/boil. The temperature that it melts at is the same that it freezes at. Likewise with condensing and boiling.
Does higher boiling point mean lower freezing point?
The boiling point of a solution is higher than the boiling point of a pure solvent, and the freezing point of a solution is lower than the freezing point of a pure solvent. For example, the boiling point of pure water at 1.0atm is 100oC while the boiling point of a 2% saltwater solution is about 102oC.
