Neither are actually points as such, but lines on a scale comparing temperature and pressure. Increase one and the size of the other goes up as well before the material will change state. So in effect, yes, the points do change, depending on the environment they are in at the time.
What else can I help you with?
How does the melting and boiling point of a substance change?
it changes depending upon the temperature
What is the boiling melting and freezing point?
A boiling point is a point on the temperature scale at which a substance begins to boil. A melting point is a point on the temperature scale at which a substance freezes. Melting and boiling points are unique to different types of elements.
Will there be effect on melting or boiling point of a substance if another substance is added to it?
Yes, impurities have important effects on the melting and boiling point of materials.
What point does it become a liquid?
The boiling point of a substance is the point at which that substance will change between being a gas and a liquid. For example, the boiling point of water is 100oC, so water vapour will change to water at this temperature. The boiling point of Methane is -161oC, so any temperature above this, Methane will be in gas form.
How can a substance have no melting point or boiling point?
Example: compounds that are thermally decomposed before a supposed melting or boiling point.
Do the melting point and boiling point of a substance ever change?
These values depends (specially the boiling point) on the pressure.
What change of state occurs when a substance reaches it's melting point. What occurs when it reaches it's boiling point?
When a substance reaches its melting point it changes from solid to liquid. When a substance reaches its boiling point it changes from liquid to gas.
How does the melting and boiling point of a substance change?
it changes depending upon the temperature
How does boiling point and melting point find a substance?
The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid. These properties are unique to each substance and can be used to identify or characterize them.
What is the boiling melting and freezing point?
A boiling point is a point on the temperature scale at which a substance begins to boil. A melting point is a point on the temperature scale at which a substance freezes. Melting and boiling points are unique to different types of elements.
Will there be effect on melting or boiling point of a substance if another substance is added to it?
Yes, impurities have important effects on the melting and boiling point of materials.
Is boiling point is always same as the melting point?
No, the boiling point and the melting point are not always the same. The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid.
Are melting and boiling point physical properties of a substance?
Yes, melting and boiling points are physical properties of a substance. They represent specific temperatures at which a substance transitions from one phase to another - solid to liquid for melting point, and liquid to gas for boiling point.
How do you identify the change of state a substance is undergoing?
through it's boiling, melting, and freezing point.
What is the meaning when something is boiling or melting?
Boiling occurs when a substance changes from a liquid to a gas at its boiling point, while melting happens when a substance changes from a solid to a liquid at its melting point. Both processes involve an increase in temperature that causes the substance's molecules to gain enough energy to overcome intermolecular forces and change states.
What point does it become a liquid?
The boiling point of a substance is the point at which that substance will change between being a gas and a liquid. For example, the boiling point of water is 100oC, so water vapour will change to water at this temperature. The boiling point of Methane is -161oC, so any temperature above this, Methane will be in gas form.
