Question

A mixture does not have definite physical and chemical properties.

• A. True
• B. False

Answer 1

The correct option is A True

• A mixture does not have definite physical and chemical properties.
• There is no energy absorbed or released during the formation of a mixture.
• The constituents of a mixture are not present in a definite ratio.
• The composition of a mixture is variable.
• For instance, the amount of carbon dioxide and water vapor present in the air may vary from place to place.
• There is no chemical reaction taking place amongst the constituents of a mixture.
• The forces of attraction holding the constituents are weak due to which the constituents can be separated using simple methods.
• For example, we can separate a mixture of sand and water by filtration.
• The constituents of a mixture retain their original properties. For example, air supports combustion due to the presence of oxygen which is one of its constituents.
• A mixture does not have a fixed melting or boiling point.
