Question

Particles of matter possess kinetic energy and they are in constant motion.  


  1. False

  2. True


Solution

The correct option is B

True


The above statement is true. Suppose an un-lit incense stick (Agarbatti) is present in a corner of your room, it hardly smells. Upon lighting it, one can smell it all over the place. This shows particles of incense stick are continuously moving throughout the room in a random motion, which means particles possess kinetic energy. Lighting the incense stick increases the temperature in the local area (tip of the stick) which gives more kinetic energy to the particles of the stick to spread in the room.
