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 when there is a very strong attractive force between particles?
The attractive forces between particles are strong enough to hold a specific volume but not strong enough to keep the molecules sliding over 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.
Do forces between particles increase as the particles move faster and farther apart?
Strong attractive forces hold slow-moving particles close together, as shown in the figure below. As the motion of particles gets faster, particles move farther apart. When they get farther apart, the attractive forces between particles have a weaker effect. The spaces between them increase.
Which state of matter has the weakest attractive forces between its molecules?
Molecular solids have lower melting points because attractive forces are weaker.
How does particle speed relate to the distance between particles?
The vibrational motion of particles in solids is kinetic energy. Heat makes the particles in a solid vibrate faster, giving them more kinetic energy. Faster-vibrating particles bump into one another more often and hit each other harder. This pushes the particles farther apart.
How fast do particles move?
The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature. The oxygen and nitrogen molecules in air at normal room temperature are moving rapidly at between 300 to 400 metres per second.
What is the strongest intermolecular force?
The strongest intermolecular force is hydrogen bonding, which is a particular subset of dipole-dipole interactions that occur when a hydrogen is in close proximity (bound to) a highly electronegative element (namely oxygen, nitrogen, or fluorine).
Is plasma a particle?
plasma, in physics, an electrically conducting medium in which there are roughly equal numbers of positively and negatively charged particles, produced when the atoms in a gas become ionized. It is sometimes referred to as the fourth state of matter, distinct from the solid, liquid, and gaseous states.
Which of the following substances has the strongest force of attraction between the particles?
The forces of attraction between the particles in a solid are the strongest, in liquids are less strong whereas in gases are the weakest.
Do solid particles move fast or slow?
Solids – vibrational (and rotational); moving very slowly. Liquids – vibrational, rotational, and translational; moving quickly. Gases – vibrational, rotational, and translational; moving very quickly.
What happens to the speed of the particles if the size of the object gets bigger?
What happens to the speed of the particles if the size of the particle is increased? It goes slower or it slows down. What do you have to do to give the particles of the matter the most kinetic energy? Increase the mass with constant velocity, increase the velocity with constant mass, or both.
Why do large particles move slower?
In other words: if we have more mass, we’ll have less velocity, or speed. … This means that larger particles with more mass have less speed. Smaller particles with less mass have more speed.
