34. When incense stick is lighted in the corner of a room , it's fragrance spreads quickly in the entire room because on heating the kinetic energy increases . Therefore , as the incense stick is lit the particles moves faster in the air as kinetic energy increases on heating .
35. Key Points
Matter can exist in one of three main states: solid, liquid, or gas.
Solid matter is composed of tightly packed particles. ...
Liquid matter is made of more loosely packed particles. ...
Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.
36. Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.
