Study the figures given below and answer the questions that follow. 1. Why does air enter in (ii)? 2. Why does the candle get extinguished when covered with a glass jar? 3. When the candle gets extinguished, why does the level of water rise in the inverted jar (ii)?

1. When the glass is tilted, the air present in the glass is rapidly replaced with water. 2. For burning, oxygen is required. When covered, the candle does not get access to oxygen, hence it extinguishes. 3. When the candle extinguishes, the temperature inside the jar decreases and the temperature drops. To equalise the pressure, water enters into the jar.

Answer

When the glass is tilted, the air present in the glass is rapidly replaced with water.

For burning, oxygen is required. When covered, the candle does not get access to oxygen, hence it extinguishes.

When the candle extinguishes, the temperature inside the jar decreases and the temperature drops. To equalise the pressure, water enters into the jar.
