Question

When water is filled in a bottle and allowed to freeze, the bottle breaks because:

  1. Water expands on freezing
  2. Bottle contracts at freezing point
  3. Temperature outside the bottle is more than inside
  4. Water expands on heating

Answer:

Option A: Water expands on freezing

Detailed Solution:

The correct answer is “Water expands on freezing”.

When water freezes, it expands and occupies a larger volume. This increased pressure on the bottle's walls eventually causes it to break.
