In winter when you touch a log of wood and a rod of iron, you will feel that rod of iron is colder than wood because –
- AThe heat of rod of iron is less than the heat of log of wood
- BIn comparison to wood, iron is good conductor of heat
- CIn comparison to wood, iron is bad conductor of heat
- DThe rod of iron is heavier than the log of wood
Show answer and explanation
Correct answer: (b) In comparison to wood, iron is good conductor of heat
Explanation
Both the iron and the wood are at the same temperature. Iron is a good conductor of heat, so it draws heat from your hand quickly and feels colder.
Wood is a poor conductor, so it takes heat from your hand slowly and does not feel as cold.
