What state of matter is the cloudy stuff above the surface of boiling water?
Differences between evaporation and boiling?
Evaporation of a liquid can take place at the interface of the liquid with a gas phase, and the liquid does not need to be saturated (at its boiling temperature). In boiling evaporation takes place at the interface of the liquid and the solid surface that is providing the heat for the process. The heating surface requires to be at a temperature above the liquids boiling temperature to produce the heat transfer, and the liquid gets heated some degrees above its boiling temperature at least in about a small film over the heating surface called superheated thermal layer, where bubbles are formed in case of nucleate boiling. Higher heating surface temperature can produce what is called film boiling where the liquid doesn't touch the heating surface at all.

What do boiling point and melting point have to do with the phase of matter of an element at room temperature?
The state of matter of a substance at room temperature depends on whether the melting and boiling points are above or below room temperature. At room temperature: A substance is solid if both the melting and boiling points are above room temperature. A substance is liquid if the melting point is below room temperature but the boiling point is above room temperature. A substance is a gas if both the melting point and boiling point are below room temperature.
Is it true that particles can only evaporate from a liquid at temperatures above liquids boiling point?

How a liquid can be changed to gaseous form below its boiling point without supplying it with heat energy?
Asked in Chemistry, Temperature
How can information about the melting point and boiling point of matter help you know its state?
If the temperature is below the melting point, you know it is in the solid state. If the temperature is below the boiling point, and above the melting point, you know it is a liquid. If the temperature is above the boiling point, you know it is a gas, etc. (Note: melting point is the same as freezing point).

What is the relation of vapor in boiling water?
How does evaporation differ from boiling?
Evaporation is much slower than boiling, and it can happen at any temperature (above zero Kelvin) whereas boiling only happens at the boiling point. Evaporation happens when a liquid molecule has enough energy to escape from the surface of a liquid - this is why you can smell perfume and why puddles disappear in warm weather As these molecules build up above the surface of the liquid, there is a build up of pressure. This is called the saturated vapour pressure. When the overall temperature of the liquid is high enough, the saturated vapour pressure increases until it is equal to atmospheric pressure - this is called the boiling point.

What is the phase change from a liquid to a gas?
The phase change for liquid to gas is vaporization, which includes evaporation and boiling. Evaporation - The change of liquid molecules on the surface of a liquid to a gas. Boiling - The change of phase at or above the boiling point of the liquid, which takes place at nucleation sites within the liquid.

Asked in Physics, Chemistry, Snow and Ice
Why does ice develop on your car overnight even if the outdoor temp is above 32 degrees Fahrenheit 0 degrees celsius?
Frost (or ice) on a surface develops when the surface is below freezing temperature, and the dew point temp. is above the surface temp. This combination will create frost. Also frost is more likely to occur on a clear night than on a cloudy one because the clouds help form a blanket that keeps heat in.
