Which of the following statements is not a correct assumption of the classicalmodel of an ideal gas? a. the molecules are in random motion. b. the volume of the molecules is negligible compared with the volume occupied bythe gas. c. the molecules obey newton's laws of motion. d. the collisions between molecules are inelastic. e. the only appreciable forces on the molecules are those that occur duringcollisions.

The answer is D, because the collision's between molecules are elastic, not inelastic.

D! because the collision's between molecules are elastic, not inelastic.

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts

a.) travels faster in solids because the particles are closer together.
