Question

The melting point and boiling point of a mixture are

  1. Always fixed
  2. Does not fixed
  3. Depends on the proportion of components
  4. Independent of the proportion of components

hintHint:

Depends on the proportion of components

The correct answer is: Depends on the proportion of components


    • A mixture is a composition composed of two or more distinct ingredients. A mixture is a physical mixture of two or more substances in which the constituents retain their identities. The combination of chemical substances such as elements and compounds is known as a mixture.
    • The melting point of a substance is the temperature at which a substance changes state from solid to liquid. A mixture is made up of more than one ingredient. When a combination contains more solutes, the melting and boiling points of the mixture vary.
