It's because substances have different boiling point and freezing point. By finding the exact boiling point and freezing point, you can identify a substance.
Keep in mind that a material's melting point is the same as its freezing point. These are just different terms for the same thing, it just depends on whether energy is being removed from a substance (freezing) or if energy is being added to a substance (melting). The same thing also applies to the boiling/condensation point.
The difference between the freezing and boiling points vary from substance to substance.
boiling points are when a substance starts to boil. example- water 32degrees F A boiling point is when a liquid evaporates to form a gas. freezing points are when a substance starts to freeze. example- water 212degrees F A liquid freezes to a solid below its freezing point.
Boiling and freezing points of a substance are affected by pressure. An increase in pressure raises the boiling point and lowers the freezing point of a substance. Melting point is not significantly affected by pressure.
No, they are different. For example: The freezing point of water is 32 degrees Fahrenheit, while the boiling point is 212 degrees Fahrenheit.
No, boiling points and freezing points are not chemical changes. They are physical properties of a substance related to its phase transition between solid, liquid, and gas states. Chemical changes involve the formation of new substances with different chemical properties.
Melting and boiling points are physical properties unique to each substance, so knowing these values can help identify a substance. By comparing the observed melting and boiling points of an unknown substance to known values in a database, you can narrow down the possible identities of the substance. Substances with similar melting and boiling points are more likely to be the same compound.
I dont know, go look in your science book
The freezing point is the temperature at which a substance transitions from a liquid to a solid state, while the boiling point is the temperature at which a substance transitions from a liquid to a gas state. These points are characteristic properties of each substance and can vary depending on the type of substance.
Boiling point and freezing point are examples of physical properties of a substance, specifically referring to the temperature at which a substance transitions between different states of matter. Boiling point is the temperature at which a substance changes from a liquid to a gas, while freezing point is the temperature at which a substance changes from a liquid to a solid.
No, boiling points and freezing points are examples of physical properties, not chemical properties. Chemical properties describe how a substance interacts with other substances to form new substances, while physical properties describe characteristics that can be observed without changing the chemical composition of the substance.
Because each compound has a specific boiling point (with some exceptions) comparing exactly determined boiling points we can identify compounds.
It means that the freezing or melting points do not change, that they are always the same, depending on the type of matter. For eg. the melting point or freezing point of water is 0○ Celsius and the boiling point is always 100○C.
