In the accompanying cylinder diagram, a chemical process occurs at constant temperature and pressure. (a) Is the sign of w indicated by this change positive or negative?
Consider the two diagrams that follow. (d) Would similar relationships hold for the work involved in each process?
(b) Why does increasing the temperature cause a solid substance to change in succession from a solid to a liquid to a gas?
(b) What is the change in potential energy if the distance separating the two electrons is increased to 1.0 nm?
(c) Does the potential energy of the two particles increase or decrease when the distance is increased to 1.0 nm?
(a) The electrostatic force (not energy) of attraction between two oppositely charged objects is given by the equation F = k (Q1Q2/d2) where k = 8.99⨉109N-m2/C2, Q1 and Q2 are the charges of the two objects in Coulombs, and d is the distance separating the two objects in meters. What is the electrostatic force of attraction (in Newtons) between an electron and a proton that are separated by 1⨉102 pm?
