ül. A piece of metal becomes hot when it lies in the sun through:
* Radiation
* Convection
* Conduction
* None
Answers
Answer:
your answer is radiation
A piece of metal becomes hot when it lies in the sun through Radiation.
Answer:
1. When a piece of metal is kept under the sun for a sufficient time, the metal piece gets heated up and becomes hot by the process of radiation.
2. So, the correct choice of the asked question is Radiation.
3. The thermal energy which is produced from the sun heats up the air, ground and other objects (especially those materials that are good conductors of heat).
4. When this energy reaches the object, the atoms which makes up the structure of the object gets heated up. This results in the movement and bumping of these atoms into other atoms. This leads to energy transfer and the object (metal piece) becomes hot.
5. Metals are good conductors of heat and hence becomes hot but when wooden objects are placed under sun, they do not get heat up as wood is a bad conductor of heat.
