Explanation / Answer
Video Link missing in the 1st question , hence i Cant answer the 1st question(please do comment the video link in the comment, I ll answer the 1st question later then)
2. Which of the following is not true regarding the transfer of heat energy?
Answer: Air conducts heat effictively.
Explanation: Air is a bad conductor of heat as the molecules in the air are far away from each other when compared to a solid , hence the energy transfer is not as effiecient in a solid. Therefore air is a bad conductor of heat.
3. Of these means of transferring heat, which tend directly produce weather systems?
Answer: Convection
Explanation: Convection process is transfer of heat by the movement of fluids. The earth's atmosphere is mostly made up of fluids like air and water vapour(air is mentioned as a fluid here because it has the ability to flow, hence called a fluid). The temperature differences in the atmosphere directly govern the weather changes in a particular area, since convection is the main form of energy transfer in fluids, convection in the atmosphere directly produce weather system.
P.S : Any doubts in the answer, please feel free to ask. Please post link to the video sp that i could answer question 1 too. Thanks!! Cheers!!
