HELP ASAP PLS Explain how an electric current can travel through conductive materials. Identify three different materials: one that is a good conductor, one that is semi-conductive, and one that is a good insulator. Explain why each material possesses its specific properties and suggest an application for its use in everyday life.

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
