Question:
A sealed glass jar is full of water. When its temperature is decreased to \(0^\circ C\),
A sealed glass jar is full of water. When its temperature is decreased to \(0^\circ C\),
Show Hint
Water expands on freezing, so a sealed container filled with water may break when water turns into ice.

- The glass jar remains as it is with ice
- The glass jar remains as it is with water
- Glass jar contains half the amount of ice mixed with water
- The glass jar breaks due to the formation of ice
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Water shows anomalous expansion. When water freezes into ice, its volume increases.
Step 1: The glass jar is completely filled with water and sealed.
Step 2: When the temperature is decreased to \(0^\circ C\), water starts changing into ice.
Step 3: Ice occupies more volume than liquid water.
Step 4: Since the jar is sealed, there is no extra space for expansion.
Step 5: Therefore, the pressure exerted by expanding ice on the walls of the glass jar increases.
Step 6: Due to this pressure, the glass jar breaks. \[ \boxed{\text{The glass jar breaks due to the formation of ice}} \]
