An ideal gas occupies a volume of 0.60 m3 at 5.0 atm and 400. k. what volume does it occupy at 4.0 atm and a temperature of 200. k? what is the known and unknown when using p1v1/t1=p2v2/t2

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.
