it is difficult to break a piece of rock because
1)Rock has particles in it
2)Rock has space between their particles
3)Rock has high intermolecular force
4)Particles of rock moves in random direction
Answers
It is very difficult to break a piece of rock because
3)Rock has high intermolecular force:
At first we can explain it by giving definition:
As we know that rocks are in solid state. The molecules in solids are very closely packed. It has strong force of attraction. There is no gap between it's particles. Due to high intermolecular force a solid matters are very hard and difficult to break them.
There are three states of matter which is found in nature.
They are in the form of solid, liquid and gas.
The molecules in liquid are loosely packed. It has no fix shape and volume. The intermolecular force are weak. Due to weak force of attraction it starts floating on the surface of the earth.
The molecules in gas are very loosely packed. It has no shape and volume. There is very far gap between it's particles. Due to it rises up in the air and spread easily around us.
