1. Fluorine

2. Iodine

3. Mercury

4. Bromine

Q.

C. Match the statements in column A with those in column B.

Column 1	Column 2
Force of attraction in between the molecules of matter	Matter
Spaces in between the molecules of matter	solid
Any material which occupies spaces and has mass	liquid
A state of matter which is incompressible	intermolecular force
A state of matter which can have only one surface	intermolecular spaces

Q. Fill in the blanks:​

Gases are ________ dense.​

Q.

Give two examples of elements which exists as;

(a) solid (b) liquid ( c) gas, under normal conditions.

Q.

Pick the odd one out: water, wood, sound, air

Q.

In which of the three states of matter- solids, liquids or gases is the movement of atoms about their own position. Give a reason for the same.

Q.

Which among the three physical states of matter has the maximum intermolecular force?

Q.

11 (b). A material A can exist in three physical i.e. solid, liquid, and gas. No living thing on earth can exist in the absence of this material. It falls from the clouds in the form of B. Lack of B for long period in an area may cause C whereas an excess of B may cause D.
