Consider a system composed of four differently colored particles and two boxes ( box A and box B). Let the initial macrostate be such that all particles are in box A and the final microstate be two particles in box A and two particles in box B. During the process entropy will:a. Increaseb. Decreasec. Remain unchanged.

Awoman stands a distance d from a loud motor that emits sound uniformly in all directions. the sound intensity at her position is an uncomfortable 2.0×10-3 w/m2. at a distance 2.6 times as far from the motor, what are (a) the sound intensity and (b) the sound intensity level relative to the threshold of hearing?

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?
