an open vessel contains 0.3 mol of chloroform (chcl3) that is heated from 240 k to 330 k. calculate the entropy change associated with this process assuming that the molar heat capacity of chloroform over this temperature range is a constant, with a value of 113.8 j k–1 mol–1. also assume that the volume does not change.​

a. a primary source combines several different accounts of an event. b. a primary source generally benefits from having been written after an event.

explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
