Question

give two reasons to justify that : a)water is a liquid at room temperature b) an iron almirah is a solid.

Answer 1

HOLA !!

-------------------------

Now , the intermolecular space is moderate in water they are not closely packed and also not so unclose that they can move independently so water is moderate hence they are liquid at room temperature having there characteristic

Case 2 -- Iron almirah is solid

How ?

Simple , intermolecular space is very less hence they are closely packed

HOPE U UNDERSTAND

Answer 2

1.Because it does not have fixed shape...so it takes the shape of the container in which it is kept ..it has fixed volume
2. Because it has fixed shape n fixed volume..solids are incompressible if we apply force on iron almirah it will not reduce its shape..
