How does a substance's boiling point determine its state at room temperature?
A substance's boiling point indicates the temperature at which it transitions from a liquid to a gas. If the substance's boiling point is below room temperature, it will be a gas at room temperature. If the boiling point is above room temperature, it will be a liquid at room 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.
Why is pressure required to kill endospores in an autoclave?
Pressure increases the boiling point of water, when it does boil the steam is now 'super-heated'. It is at a higher temperature than the boiling point of 100C (usually 121C and 15psi for an autoclave) this quickly transfers much greater amounts of heat energy to the object being autoclaved. The vast majority of microorganisms and even pathogenic bacterial spores cannot withstand this temperature and pressure for long, the lipids and proteins in their cell walls and membranes disintegrate and they are killed.
Why the temperature inside an autoclave can be higher than 100 Celsius?
The temperature inside can be higher than the boiling point of water due to pressure; it is all relative. For instance at sea level water boils at 100 C / 212 F; but on top of Mount Everest it boils at 69C / 156 F. An autoclave runs at 30~35 PSI which translates to water boiling at 135C / 280F to 160C / 320F. The higher the pressure the higher the temperature.
Are there more water vapor molecules above a beaker of water at room temperature or a beaker of water at its boiling point?
There are more water vapor molecules above a beaker of water at its boiling point because the higher temperature causes more water molecules to evaporate into the air. This results in a higher concentration of water vapor over the boiling water compared to room temperature water.
How can the temperature in the autoclave go above boiling temperature of 212 F?
The temperature in an autoclave can go above the boiling temperature of 212°F by increasing the pressure inside the autoclave. As pressure increases, the boiling point of water also increases. This allows the autoclave to achieve temperatures higher than the standard boiling point of water.
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.
How does a substance's boiling point determine its state at room temperature?
A substance's boiling point indicates the temperature at which it transitions from a liquid to a gas. If the substance's boiling point is below room temperature, it will be a gas at room temperature. If the boiling point is above room temperature, it will be a liquid at room temperature.

How can information about the melting point and boiling point of matter help you know its states?
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 melting and boiling point of ice?

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 temperature does jam need to get to before it boils?
When the jam has reached 8 degrees above boiling point, the jam has reached it's boiling point.
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.
