What is difference between gas and Vapour?
Vapour is a mixture of two or more different phases at room temperature, these phases are
liquid and gaseous phase
. Gas usually contains a single thermodynamic state at room temperature. … Gas also consists of random molecules and atoms moving about randomly. Vapour is not a state of matter, unlike gases.
What is difference between Vapour and steam?
Vapor is a
type of gas
while steam, in return, is a type of vapor. … To put it simply, a solid or liquid substance can change into gas, and that resulting gas is called a vapor. On the other hand, steam is a technical term for water vapor or water in a gaseous state. It is also one of the most common examples of a vapor.

What is melting point Class 9?
Hint: Melting point of substance is
temperature at which it melts or the temperature at which solid is converted into liquid
. Example: Melting point of ice is 0∘C it means at 0∘C ice converted into water. Complete answer: … At melting point, the solid and liquid phase exist in equilibrium.
