Answer 1

Answer:

5Intermolecular spaces are spaces between the molecules of matter

6if you spray a perfume in the whole room the molecules of perfumes(gas) will move freely in any direction therefore imtermolecular sapcing exist

7 Intermolecular force is the force with which a molecule attract another molecule toward itself

9 molecules are in random motion

they attract each other

they qve Intermolecular space between them

10 solid -solid have a definite size

solid have a definite shape

solid have a fixed density

liquid- liquid have a definite size

they do not have a definite shape

they are less denser tan solid

gas-gas do not have a definite size

they do not have a definite shape

they are the least denser
