Question

how can we demonstrate the transfer of heat by conduction in a solid​

Answer 1

Answer:

Explanation: Take a few rods each made of a different substance (for example, three different metal rods). Attach some wax to the end of each one, and then stick a coin onto the wax. Heat up all three rods equally. If the metal is a good conductor of heat, the wax will melt fairly quickly (because the heat will have passed all the way through the rod), dropping the coin. If the metal is not a good conductor, the wax will take longer to melt. You can put different substances in order of conductivity by measuring how much time it takes for the coins on each one to fall off.
