Answer #1

Resistivity for a material can be defined as the resistance offered by a conductor made up of that material having unit length and unit cross sectional area, against the flow of current.

This resistance occurs because of the collision of free electrons at intermolecular level. When plastic deformation occurs in the metallic body its molecular structure, intramolecular distances , lattice structure and Molecular geometry changes due to which the resistance offered against against the flow of current also changes this is why plastic deformation causes change in resistivity of a material.

A region where no magnetic field is desired is surrounded by a sheet of low-resistivity metal.? A) Will this sheet shield the interior from a rapidly changing magnetic field outside? B) Will it act as a shield to a static magnetic field? C) What if the sheet is superconducting (resistivity = 0)? Answer 1: The superconducting sheet will shield the interior from magnetic fields. Answer 2: The superconducting sheet will not shield the interior from magnetic fields.

A common way to make hydrogen in the labratory is to place a metal such as zinc in hydrochloric acid. The hydrochloric acid reacts with the metal to produce hydrogen gas, which is then collected over water. Suppose a student carries out this reaction and collects a total of 154.4 mL of gas at a pressure of 742 mmHg and a temperature of 25 degrees Celcius. What mass of hydrogen (in mg) does the student collect?
