Answer 1

Answer:

point no (d) is wrong as now atoms can be further divided into electron proton and neutron

FILL IN THE BLANKS

(1) 2,1

(2) INTERMOLECULAR SPACE

(3)BROWNIAN motion

(4) molecular

ANSWER THE FOLLOW QUESTIONS

(1) because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. The amount of a substance that can dissolve in a liquid (at a particular temperature) is called the solubility of the substance.

(2)We can break a piece of chalk easily because particles of matter in a chalk are somewhat loosely packed. While in the case of an iron piece, the particles of matter are very very tightly packed and it requires great great force to break it up into pieces

1) a)

2)particle

• 2atoms of hydrogen and1 atom of oxygen
• intermolecular space
• kinetic motion
• kinetic force

1)because particles of water have space between them so the water does not rise up when salt is added to water

2)it is easy to break down the pieces of chalk but not the iron nail because of its force of attraction
