The global Covid - 19 pandemic unexpectedly entered our lives and put everything to a halt. It affected the lives of people around the world bringing a flood of tension and worries followed by negative thoughts and piles of boredom. But I took it as a challenge to handle this situation with determination and positivity thereby taking advantage of the lockdown. My parents motivated me to complete this challenge. The lockdown has affected my life quite disturbingly. My first priority, Taekwondo Federation of India National - Level Championship, scheduled in March got postponed. I desperately wanted to win a national gold medal in taekwondo for the second time. Another high valued South Asian Cup Martial Arts Championship in Nepal that was due in Feb - March 2020 also got delayed. I was really looking forward to more tournaments in 2020. But my coaches have not let my fitness get off the track as I am enjoying virtual classes
Take a rod or flat strip of a metal, say of aluminium or iron. Fix a few small wax pieces on the rod. These pieces should be at nearly equal distances. Clamp the rod to a stand. If you do not find a stand, you can put one end of the rod in between bricks. Now, heat the other end of the rod and observe.
The process by which heat is transferred from the hotter end to the colder end of an object is known as conduction. In solids, generally, the heat is transferred by the process of conduction.
Do all substances conduct heat easily? You must have observed that the metallic pan for cooking has a plastic or wooden handle. Can you lift a hot pan by holding i t from the handle without getting hurt?
