For every liquid there is a temperature above which the kinetic activity of its molecules is so great that the attractive forces cannot keep them in a liquid state this temperature is called?
Critical temperature
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.
How can the temperature in the autoclave go above the boiling point of water?
Because the pressure is higher.
How does the boiling point of a liquid at sea level compare to the boiling point of a liquid on top of a mountain?
A liquid boils when the molecules are going fast enough to create vapor pressure equal to the atmospheric pressure. The higher the temperature, the faster the molecules are moving. Temperature measures the average kinetic energy of the molecules. So when you heat water to make it boil, you are actually providing enough heat energy to be converted into kinetic energy, so the molecules are moving fast enough, to produce enough vapor pressure to push the air out of the way, so the water molecules can get out of the water and into the air. (What a run on sentence) So when you go up on top of a mountain where the air pressure is less, so it is easier for the water molecules go fast enough to produce enough water vapor pressure to push the air molecules out of the way. So the Boiling point for a liquid on top of a mountain is lower than for the same liquid at sea level. I wonder if any teachers besides me tell students that the air molecules above a pan of water are colliding with the water molecules in the pan, so the water molecules can not produce ……
Is it true that particles can only evaporate from a liquid at temperatures above liquids boiling point?
It is not true; evaporation occur at the surface of a liquid and the temperature is under the boiling point.

boiling point

Critical temperature
What are 5 liquids that do not have water?
-- pure alcohol at room temperature -- mercury at room temperature -- oxygen below its boiling temperature -- iron above its melting temperature -- nitrogen below its boiling temperature -- salt above its melting temperature -- gold above its melting temperature -- any other element or compound that is not H2O, above its melting temperature and below its boiling temperature
How can the temperature in the autoclave go above boiling temperature of 212 F?
At higher pressure the boiling point is higher.
How can you use boiling points and melting points to determine a solid liquid or gas that an element would be in at a certain temperature?
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.
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.
How can water in an engine stay a liquid when the temperature is above its normal boiling point?
The cooling system is pressurized and requires a higher temperature to reach boiling.
What is the melting and boiling point of ice?
any temperature above zero.
What happens at a liquid's boiling point?
Boiling. A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it.
How does boiling from evaporation?
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.
How can the temperature in the autoclave go above the boiling point of water?
Because the pressure is higher.
On the Celsius scale what temperature is twenty degrees above the boiling point of water?
120oC
