All of the following statements are correct EXCEPT Select the correct response: in any chemical reaction the change in energies of the system and the surroundings are equal in magnitude but opposite in an expanding gas does work on the surroundings, thus w has a negative value. if a reaction occurs at constant pressure, w = E E = q + w (where q equals heat and w equals work). if a reaction occurs at constant volume, q = E. < Previous There will be work done if the direction of the force is perpendicular to the direction of displacement Select the correct response. none of the choices False Both True If during a given physical process the only force acting on an object is friction, which of the following must be assumed in regard t kinetic energy? Select the correct response: x It decreases. It increases It remains constant It cannot be determined from the information given
