Why are the melting point and boiling point of the same matter different?
Boiling point is the temperature at which a substance turns into a gas, while melting point is the temperature at which a substance turns into a liquid state from a solid state. The boiling point is always a higher temperature then the melting point. The melting point has a substance turn into a liquid from solid, and boiling point has a liquid turn into a gas.
How do evaporation and boiling different?
Evaporation occurs at the surface of a liquid, where individual molecules escape into the air, while boiling happens throughout the bulk of the liquid, with bubbles forming and rising to the surface. Evaporation can occur at any temperature, while boiling specifically happens at the boiling point of a liquid.
What bubbles mean when water's boiling?
When water is boiling, the bubbles are formed by the water vaporizing into steam. As the water reaches its boiling point, it transitions from a liquid to a gas, creating bubbles that rise to the surface and release steam into the air.
Vaporization that occurs on and below the surface of a liquid?
This process is called evaporation, where molecules escape from the liquid's surface into the air. Evaporation occurs at temperatures below the liquid's boiling point.
What is the name for the temperature when liquid turns into a gas?
It's called the boiling point. It is the temp where the vapor pressure of the "liquid" is equal to the air pressure around (above) it. This is when the liquid [water] reaches 100 degrees Cecilius [at sea level].
When water is boiling does it change from liquid to gas?
Yes, water changes from a liquid to a gas when it is boiling. At the boiling point, the molecules of water have enough energy to overcome the intermolecular forces holding them together as a liquid, allowing them to escape into the air as water vapor.
Is boiling of liquid air a physical or chemical change?

How do boiling points affect evaporation?
Boiling point is where the vapor pressure of a liquid equals the ambient pressure. The closer you are to the boiling point, the more driving force there is for the liquid to evaporate until it saturates the surrounding air.
What should be consider when examining the boiling point?
Air pressure and pressure within the vessel containing the boiling liquid.
What bubbles mean when water's boiling?
When water is boiling, the bubbles are formed by the water vaporizing into steam. As the water reaches its boiling point, it transitions from a liquid to a gas, creating bubbles that rise to the surface and release steam into the air.
What is the boiling point water?
Boiling is the formation of vapor bubbles inside a liquid. They are not air, but rather some of the liquid that has evaporated. The molecules of the liquid have to have enough energy to break out of the liquid phase and become the vapor. That means the vapor has to push the liquid aside to make the bubble. This happens when the vapor can push back against the atmosphere pushing on the liquid. The boiling point is the temperature where the vapor has enough push to overcome the air pressure. In other words, the boiling point is the temperature where the vapor pressure and the atmospheric pressure are the same. The lower the atmospheric pressure, the lower the boiling point.
Vaporization that occurs on and below the surface of a liquid?
This process is called evaporation, where molecules escape from the liquid's surface into the air. Evaporation occurs at temperatures below the liquid's boiling point.
The boiling point is the temperature at which a substance changes from what?
Boiling point refers to the temperature at which a liquid boils and becomes a gas. This temperature varies according to;The substance in questionThe pressure of the surroundings
What type of liquid does not have a boiling point?
All liquids have an eventual boiling point, some of them are just incredibly hard to do because of the extreme amount of heat needed. Boiling a liquid is just the process by which atoms of the substance are heated enough to have enough energy to break free from the molecular bonds of the surface of the liquid and float into the air as a gas.
What is the vaporization called below the surface of a liquid?
The process of vaporization below the surface of a liquid is called "boiling." When a liquid reaches its boiling point, bubbles of vapor form within the liquid and rise to the surface, where they are released into the air.
