Take all the above objects and try hammering them, stretching or breaking them. You will observed that you find it easy to break a chalk, little tougher to break rubber band and toughest to break a coin. Conclusion: Particles of matter attract each other.
What causes the particles to be attracted to each other?
Gravity is the force that all objects with mass exert upon one another, pulling the objects closer together. … There are several kinds of forces that particles can exert on one another. These forces can cause one particle to attract, repel, or even destroy another particle.
How do you prove that particles of water attract each other?
Open the tap and try to cut the water using your finger or knife. you will see that water again connects and starts to flow. this shows that water particles attract each other.
What kind of particles attract each other?
Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.
Do all particles have an attraction to each other?
The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles.
What is the relationship between particles in matter?
The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
How do we define momentum of a particle?
The momentum of a particle is defined as the product of its mass times its velocity. It is a vector quantity. The momentum of a system is the vector sum of the momenta of the objects which make up the system.
How will you demonstrate that particles of matter are very small?
Matter is made up of very small particles: All matter is made up of very small particles that are not visible to naked eye. We can prove this by performing the following experiment: Take two or three crystals of potassium permanganate and add in 100ml of water. We will see that the colour of the water gets changed.
How do atoms attract each other?
The atoms attract each other due to the force exerted by the nucleus of the atoms. In the beginning, the nuclear force (i.e. the force exerted by the protons present in the nucleus of one atom on the electrons of the other atom) dominate th repulsive forces between the electrons of the two atoms.
What is the attraction between particles in a liquid?
In a liquid, intermolecular attractive forces hold the molecules in contact, although they still have sufficient KE to move past each other. Intermolecular attractive forces, collectively referred to as van der Waals forces, are responsible for the behavior of liquids and solids and are electrostatic in nature.
What is the force of attraction between particles of matter?
The force of attraction between the molecules of matter is called the intermolecular force of attraction.
