1) Deserible brownian motion. in chemistry. No spam plz dear.
2) Explain why solids have fixed shape but liquids and gasses do not have fixed shape.
No spam plz dear.

Answer:
Brownian motion is the continuous random movement of small particles suspended in a fluid, which arise from collisions with the fluid molecules. First observed by the British botanist R. Brown (1773-1858) when studying pollen particles. The effect is also visible in particles of smoke suspended in a gas.
2:- Because the particles in liquids are very close together (barely further apart than in solids) liquids do not easily compress, so their volume is fixed. Gases can also flow, so occupy the shape of their whole container. They do not have a fixed shape. ... Gases therefore can be compressed or expanded.
plz rate me
Answer:
Explanation:
Solids donot have any volume nor shape that why when they are in motion they cannot move so they are fixed
