Question
Give reasons
Liquids and gases flow but solids do not?
Advertisements
Solution
The molecules of liquids and gases are far apart, i.e., have more gaps. The intermolecular attraction force is very less as compared to solids; hence, liquids and gases can flow, but solids do not, as gaps in solid molecules is less and the molecular force of attraction is very strong.
