CUET Preparation Today
A wooden spoon is dipped in a cup of ice cream. Which of the following observation will take place? |
Its other end becomes cold by the process of conduction. Its other end becomes cold by the process of convection. Its other end becomes cold by the process of radiation. Its other end does not become cold. |
Its other end does not become cold. |
The correct answer is option 4. Its other end does not become cold. Wood is not a good conductor of heat, and it has poor thermal conductivity. When a wooden spoon is dipped into ice cream, the heat is not efficiently conducted through the wood to the other end. As a result, the other end of the wooden spoon does not become significantly cold. Conduction, convection, and radiation require materials with good thermal conductivity to transfer heat effectively, and wood does not possess these properties to a high degree. |
