The temperature at which the particles of a substance would have no kinetic energy is a. 2,273 k. b. 0 k. c. 0 ºc. d. 273 k. answers

B) 0K

0K, also called absolute zero, is the lowest possible temperature theoretically possible (not yet reached!). It is believed that at this temperature, motion of all particles slows, and possibly stops. Also, remember that as the temperature decreases, the motion of particles also decreases. 

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.
