In a constant-volume process, 209 j of energy is transferred by heat to 1.00 mol of an ideal monatomic gas initially at 300 k. find (a) the work done on the gas, (b) the increase in internal energy of the gas, and (c) its final temperature.

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
