Why is metal a good THERMAL conductor but plastic is a worse conductor than metal? Explain. Why is tungsten not used as a fuse wire? Why is platinum used for making a resistance thermometer? Why is casting done with cast iron instead of copper?
Why is seawater a better conductor of electricity than water from a freshwater lake? Explain why diamond is an electrical insulator and graphite is an electrical conductor. Why is water a poor conductor of electricity? Why do covalent compounds not conduct electricity? How is copper (II) s...
While it is not quite as good a conductor as copper, aluminum wire can be lighter in weight and should also be considered a valuable metal when scrapping. If you come across Insulated Aluminum Wire when scrapping, it is a good idea to strip it down to make more money. Should You ...
Carbon steel pans are often much lighter than cast iron. Also, they offer a much wider variety of sizes than woks. They both (CI & CS) hold and distribute heat better than clad stainless steel pans (less well, maybe, than copper), but CS releases the heat faster when you change the ...
What makes copper good conductor but not polythene? Elastic behavior: when loads are small how much deformation occurs? What materials deform least? Why is it advised not to make a horse shoe magnet from a flexible material? What is an elastic collision? What is meant by the elastic limit ...
Why is steel the better metal to use in building construction than nickel? .Modulus of ElasticityModulus of ElasticityShear modulusShear modulus Metal Alloy GPa 10^6 psi GPa 10^6 psi Aluminum 69 10 25 3.6 Brass ...
Give the reasons that makes copper conduct electricity and heat better when compared with wood. Explain. Why do divalent metals exhibit positive hall coefficients? What are the requirements for a solid ionic conductor? Provide an example. Why is water a better shield aga...
The fundamental frequency is the function of tension in the string considered as well as the mass density of that string. Further, the frequency is the qualitative measurement of the pitch of the sound waves which corresponds to the sound level. Therefore, we can distinguish between...
Explain why copper wire is a good conductor of electricity. Why the ferromagnetic materials can be magnetized easily? Why and How sparkles occur in electric circuits ? Why are good conductors of heat also good conductors of electricity?
