What causes the attractive forces between particles in matter?
The particles that make up some matter are close together and vibrate back and forth. If the motion of particles slows the particles move closer together. This is because the attraction between them pulls them toward each other. Strong attractive forces hold particles close together.
What happens to the forces between particles in matter when energy is added or removed from the matter?
A change in phase may occur when the energy of the particles is changed. There are spaces between particles of matter. There are attractive forces between atoms/molecules, and these become stronger as the particles move closer together. These attractive forces are called intermolecular forces.
In which state of matter are the attractive forces between molecules the weakest?
Molecular solids
Which state of matter has the strongest attractive forces?
solids
What is the 6th and 7th state of matter?
There are six states of matter – solid, liquid, gas, plasma, Bose-Einstein condensate and the Fermionic Condensate. The sixth state of matter is the Fermionic Condensate. Now, to understand this… we have to start from the beginning.
What is an example of a change in state?
1 Answer. Phase changes include vaporization, condensation, melting, freezing, sublimation, and deposition. Evaporation, a type of vaporization, occurs when particles of a liquid reach a high enough energy to leave the surface of the liquid and change into the gas state.
What are the changes in matter examples?
The melted ice cube may be refrozen, so melting is a reversible physical change. Physical changes that involve a change of state are all reversible. Other changes of state include vaporization (liquid to gas), freezing (liquid to solid), and condensation (gas to liquid). Dissolving is also a reversible physical change.
What are reversible changes give two examples?
Reversible changes A reversible change might change how a material looks or feels, but it doesn’t create new materials. Examples of reversible reactions include dissolving, evaporation, melting and freezing.
Can we convert energy into matter?
Essentially, the equation says that mass and energy are intimately related. Atom bombs and nuclear reactors are practical examples of the formula working in one direction, turning matter into energy. But until now there has been no way to do the reverse, turn energy into matter.
Are changes in matter important?
As a result, when a substance absorbs enough energy then its atoms or molecules move around. And, when increase in this energy takes place then atoms tend to collide frequently with each other. Hence, it causes change in state of a substance. Therefore, changes in matter are important for the conservation of energy.
Does Matter ever go away?
It states that matter can never be created or destroyed, only changed and rearranged. They may be bonded into different molecules, or in a different state of matter, but they cannot disappear. When changes occur, energy is often transformed. However, like atoms, energy cannot disappear.
