Which of the following statements is incorrect?
The strength of the force of attraction between the particles of matter varies from one kind of matter to another.
The force acting between the particles of matter keeps them together.
The strength of the force of attraction between the particles of matter is constant, irrespective of the kind of matter.
The particles of matter have force acting between them.
The strength of the force of attraction between the particles of matter is constant, irrespective of the kind of matter.
The strength of the force of attraction between the particles of matter varies from one kind of matter to another. For example, the force of attraction is very strong in solids (like iron) as compared to liquids (like water) and gases (like oxygen), which is why statement C is incorrect.
The strength of the force of attraction between the particles of matter varies from one kind of matter to another. For example, the force of attraction is very strong in solids (like iron) as compared to liquids (like water) and gases (like oxygen), which is why statement C is incorrect.
Think of people holding hands: in a solid, people are locked in a tight group holding hands firmly (strong attraction); in a liquid, they are loosely linked (moderate attraction); and in a gas, they are moving freely without holding hands (very weak attraction).
SOLIDS = Strong, LIQUIDS = Loose, GASES = Gaps
Matter is made up of tiny particles that exert attractive forces on each other. These intermolecular or interparticle forces depend on the nature of the substance, determining its physical state (solid, liquid, or gas) at room temperature.
Particles of matter have spaces between them.
Particles of matter are continuously moving.
Particles of matter attract each other with a force.
The strength of this force of attraction varies depending on the type of matter.
Explaining states of matter (solid, liquid, gas)
Understanding melting and boiling points of different substances
Option C is incorrect because the force of attraction is not constant; it differs significantly between different kinds of matter (e.g., chalk vs. iron nail vs. rubber band).
C is incorrect тАФ The strength of the force of attraction between the particles of matter varies from one kind of matter to another, and is not constant.
In competitive exams like RRB ALP, questions on the fundamental properties of matter frequently test differences between solids, liquids, and gases.
