a. what is the sign of W? Negative, because work is done ON the system.b. sign of delta EpIf that means potential energy...then it is negative, because the system decreases in gravitational potential energy.c. change in KEZero, because it began at rest and ended at restd. zero, because it returned to its initial temperaturee. negative, because heat is RELEASED to the environment....
