Question 5 of 13beginner🔧 ApplyShort Answer3 marks

When spilled on the table, milk in a glass tumbler, flows and spreads out, but the glass tumbler stays in the same shape. Justify this statement.

Correct Answer

Milk flows and spreads when spilled because it is a liquid.

In liquids, the interparticle attractions are slightly weaker than in solids, allowing particles to move freely within a limited space. The particles can move past each other, enabling liquids to flow and take the shape of the container or surface.

The glass tumbler stays in the same shape because it is a solid with very strong interparticle attractions.

The particles are tightly packed in fixed positions and can only vibrate, not move freely, which gives solids their definite shape.

Explanation

The chapter explains that liquids have no fixed shape but definite volume because particles can move freely within limited space due to slightly weaker interparticle attractions. Solids have fixed shape and volume because particles are tightly packed with strong interparticle attractions, holding them in fixed positions.

Solution Steps

  1. Milk is a liquid with weaker interparticle attractions, allowing particles to move freely and flow

  2. Liquids can take the shape of the container or surface as particles move past each other

  3. Glass tumbler is a solid with very strong interparticle attractions

  4. Solid particles are tightly packed in fixed positions and can only vibrate, giving solids definite shape
