Question

arrange the following properties for solids,liquids and gases. (a) effect of pressure-increasing order. (b)empty spaces between the particles-decreasing order. (c)thermal expansion-increasing order

Answer 1

(b)empty spaces between the particles-decreasing order.(a) effect of pressure-increasing order(c)thermal expansion-increasing order
b-a-c
I hope these ans is right

Answer 2

Given solid liquids and gases. We need to arrange these three on the criteria given

a)effect of pressure-increasing order:
solid<liquid<gases.

b)Empty spaces in between particles --- decreasing order
Solids have least moelcular spaces , so
Gases>liquids >solids

c)Tendencly to flow--- Decreasing order
Only Liquids and gases will flow as they are fluids:hence
 gases>liquid >solids

d) Thermal expansion : Increasing order
Gases>Liquid>Solids
Reason: As we heat, the molecules gain K.E and move faster hence gases expand faster than solids and liquids.
