I assume the element has 5 valence electrons (not neutrons). The similar properties are shared between y and z since they have the same number of valence electrons. This is what is primarily responsible for chemical behavior.
Answer:
68.75W
Explanation:
Heat transfer is describe as the flow of thermal energy as a result of changes in temperature between two or more bodies. Heat transferred via solid bodies is called conduction, and that associated with liquids and gases is called convection, and likewise, the one attributed to electromagnetical waves is called radiation.
heat transfer from the tube wall to the water = kA.ΔT
= 3500* π* (2.5 * 10⁻²)²/4 *40
= 68.75W
