[3] (a) Characterize solid,
liquid and gases in terms of compressibility and fluidity. (Marks =
1) [3] (b) What distinguished element from a compound? Give one
example for each. (Marks = 1)
Homework Answers
(a) ✓Compressibility
Gases are highly compressible while liquids are less compressible than gases but more compressible than solids. on the other hand solids are not compressible among three physical states of matter
✓Fluidity
Gases flow most readily among three phases of matter
liquids can flow less as compare to gases but more fluidity than solids
Solids are non fluid. There are some exceptions like glasses which have very little fluidity
(b) Elements are made up of only one type of atoms for example He, H2 , P4 etc.
Compounds are made up of two or more type of elements. In compounds two or more different types of elements combine in fixed ratio by mass. For example CO2, C6H12O6
