Question

Arrange the following substances in the increasing order of the forces of attraction between their particles-
Milk, Chocolate bar, Carbon dioxide, Wooden ruler

• A. Carbon dioxide < Milk < Wooden ruler < Chocolate bar
• B. Wooden ruler < Chocolate bar < Milk< Carbon dioxide
• C. Milk < Carbon dioxide < Chocolate bar < Wooden ruler
• D. Carbon dioxide < Milk < Chocolate bar < Wooden ruler

Answer 1

The correct option is D Carbon dioxide < Milk < Chocolate bar < Wooden ruler

• The interparticle force of attraction (attraction between the particles) in solids is much higher than that in liquids, which is in turn higher than that in gases. Therefore, the order of force of attraction in matter is as follows- Gases < Liquids < Solids
• Carbon dioxide is a gas at normal temperature.
• Milk is a liquid at normal temperature.
• Chocolate and Wooden ruler are both solids at normal temperature but the force of attraction between the particles of wood in the ruler is stronger than that in the chocolate bar. A chocolate bar is much easily breakable than a wooden ruler due to stronger interparticle force of attraction in the wooden ruler.
