Observation and inference - Heat transfer — task. Chemistry CBSE Live product, Class 7 (2026-27).

Observe the following situations and select the best option that can be inferred:

1. Observe the situation:

A student notices that water in a heated pan moves continuously, while the metal pan itself remains in the same position.

Which conclusion is correct?

Neither water nor the pan transfers heat
Heat transfer in both occurs only by radiation
Heat transfer in water involves convection, while heat transfer through the metal involves conduction
Heat transfer in both occurs only by convection

2. Observe the situation:

A bukhari is burning in a room. Its iron body becomes hot, warm air rises, and a person nearby feels warmth without touching it.
