TRUE OR FALSE

6.The average kinetic energy of a collection of gas particles is assumed to be directly proportional to the Kelvin temperature of the gas.

7. The molecules move in constant, rapid, random, circular motion.

8.The  particles  are so small compared  with  the      distances between    them that the volume of the individual particles can be assumed to be zero.

9. The particles  are  assumed  to     exert no forces on each other; they are assumed neither to attract nor to repel each other.

10.The energy  of a      gas particle is lost    when it  collides with           another particle or with the walls of the container

TRUE OR FALSE

1. The kinetic molecular theory only applies to gases.

2. The collisions between air molecules use up energy and eventually make a room cooler.

3. At 35 oC, on average nitrogen molecules will move faster than nitrogen molecules at 12 oC.

4. According to KMT, gas particles have negligible mass but no volume.

5. Warming a gas results in an increase in the average kinetic energy of its particles.

7. If you get a chance to read the instructions on a bottle of deodorant, you might have read the warning signs indicating the bottle to be kept away from the sunlight and high temperature. Ever wondered why?
