boiling point
You think to vapours of a liquid.
They are the same thing. Most commonly the term melting point is used to describe the temperature at which a substance first co-exists in both a liquid and solid state. Freezing point is used usually to describe a substance that is usually liquid at room temperature, such as water. Conversely the term 'boiling point' refers to the first temperature at which the substance exists in both liquid and gaseous states.
because the they need Very HIGH TEMPERATURE TO CHANGE STATE...and we cannot supply that very high temperature
In theory, any chemical substance can achieve a gaseous state with extreme heat and/or lack of pressure. Simple table salt, for example, has a boiling temperature of nearly 2600 degrees F. Pure gold has a boiling temperature of almost 5100 degrees F. Steel, which is an alloy of iron and carbon, has a boiling temperature of 5400 degrees F. Uranium, the most massive naturally occurring element, has a boiling temperature of 6900 degrees F.
Those substances which undergo the process of sublimation change directly from solid to gas or from gas to solid. Example:- Ammonium chloride, Camphor
if the temperature of the substance is raised then the kinetic energy of the gaseous particles will also increase....
water is the substance
It is greater when the substance is at a higher temperature. This is because the mean square speed of the molecules of a system is proportional to thermodynamic temperature.
room temperature
The boiling point of a substance is the temperature at which it changes from liquid state to gaseous or vapor state.
... the substance can exist in the solid, liquid, and gaseous phases all at the same time.
The temperature AND pressure at which the solid, liquid, and gaseous state can all coexist.
You think to vapours of a liquid.
Yes, all of them.
They are the same thing. Most commonly the term melting point is used to describe the temperature at which a substance first co-exists in both a liquid and solid state. Freezing point is used usually to describe a substance that is usually liquid at room temperature, such as water. Conversely the term 'boiling point' refers to the first temperature at which the substance exists in both liquid and gaseous states.
Every substance has their own boiling point.
ALL liquid substances at room temperature become gaseous at higher (sometimes much higher) temperature called boiling point, unless they decompose at lower temperature.
