Lesson 1.1: Kinetic Molecular Model of Solids and Liquids Flashcards
It explains the properties of solids and liquids in terms of the intermolecular forces of attraction and the kinetic energy of the individual particles.
kinetic molecular model
They are attractive forces between neighboring particles of one or more substances.
Intermolecular forces
They pull the particles together.
Intermolecular forces
It keeps the particles at a distance and/or moving around.
kinetic energy
It is dependent on the temperature of the substance.
kinetic energy
It explains the behavior of particles in matter.
kinetic molecular model
It describes how the motion of particles — atoms/molecules relate to the physical properties of solids, liquids, gases.
kinetic molecular model
It is where kinetic energy is dependent on the substance.
temperature
A state of matter wherein that have definite volume but no definite shape.
liquids
A state of matter wherein it takes the shape of the container.
liquids
A state of matter that are denser than gases.
liquids
Liquids’ particles are held together by ________________________, but not strong enough to keep them in a rigid position.
strong intermolecular forces
A state of matter wherein its particles are free to slide over one another.
liquid
A state of matter that have definite volume and shape.
solids
A state of matter that are denser than liquids and are not easily compressed because their particles are tightly packed.
solids
A state of matter wherein the intermolecular forces between their particles are stronger than those in liquids, enough to keep them rigid.
solids
A state of matter wherein they assume a crystalline structure when they have a highly ordered packing arrangement.
soilds
If not in a crystalline structure because of a highly ordered packing arrangement, they exist as ______________.
amorphous solids
Example of amorphous solids
rubber and wax
A state of matter wherein one of its properties is that they do not flow.
solids
A state of matter wherein one of its properties is that they are virtually incompressible.
solids
A state of matter wherein one of its properties is that they expand when heated, but to a lesser extent than liquids and gases.
solids
A state of matter wherein one of its properties is that they are difficult to compress.
liquids
A state of matter wherein one of its properties is that they slightly expand when heated.
liquids
A state of matter wherein one of its particles is that they are strongly attracted to each other.
solids
A state of matter wherein one of its particles is that they vibrate in fixed positions.
solids
A state of matter wherein one of its particles is that they vibrate faster when heated.
solids
A state of matter wherein one of its particles is that they are weakly attracted to each other; break their interaction easily.
liquids
A state of matter wherein one of its particles is that they move more freely than those in solids.
liquids
A state of matter wherein one of its particles is that they move faster when heated.
liquids
They are the 3 characteristics of liquids.
- Fluidity
- Viscosity
- Surface Tension
A type of liquid that has an ability of a substance to flow more freely.
fluidity
Give examples of fluidity
- water flowing down a river (fluidity)
- Honey has low fluidity compared to water because it flows more slowly.
A characteristic of liquid that has a measure of a fluid’s resistance to flow
viscosity
A type of viscosity wherein a fluid flows more slowly.
higher viscosity
A type of viscosity wherein a fluid flows more easily.
lower viscosity
A characteristic of liquid that has a tendency of the surface of a liquid to contract and minimize its surface area due to cohesive forces between molecules.
surface tension
Give an example of surface tension.
