Because particles in a solid are so tightly packed together, they cannot move around freely. they can only do this.
What is vibrate?

What are the particles like in liquids?
Particles of a liquid are farther apart and they can move by sliding past each other
200
What are the 6 changes of state?
What is melting, evaporation, condensation, solidification, sublimation, and deposition?
200
What happens to matter when its temperature increases?
Its particles move around faster. The material that is made up of the particles expands. In simple terms, it increases in volume.
200
Define condensation
The change of state of a substance directly from a solid form to a gas form
200
What is the difference between heat and temperature?
Heat is a measurement of total energy in a substance and temperature is a measure of heat content of the substance.

How is a solid different from a liquid in shape and volume?
A solid is different from a liquid in shape and volume, in the sense that a solid has a fixed shape, while liquids take the shape of their container. They both have fixed volumes.

How does matter change from one state to another?
An element's state changes depending on its temperature and the pressure exerted on it. Adding or take away energy can cause it to change state
300
Why does ice float on water?
Ice floats on water because it contains less densely packed particles and water is more densely packed than ice.
300
How can you find the volume of an irregularly shaped solid?
Using the displacement method
300
What is the difference between a thermal expansion and a thermal contraction?
thermal expansion: when a material increases in volume and particles move around faster.
thermal contraction: when the matter decreases in volume and the particles take up less space as they lose energy.
300
What is the melting point and the boiling point?
The melting point: the temperature at which a solid turns to liquid.
The boiling point: the temperature at which a liquid turns to gas.

What is the change of state that is demonstrated when snow disappears without a trace on a sunny day?
What is evaporation?
400
How is melting similar to solidification? How is it different?
Melting is the change of state of a substance from a solid form to a liquid form. Solidification is the change of state of a substance from liquid form to solid form. They're the same because they both change states from a substance, but they are different, because they change from different forms.

What is kinetic energy?
What is the energy of motion
400
What is the difference between a model and a theory?
Model: a way to think about and interpret natural events and objects.
Theory: provides a scientific explanation based on the results of experimentation
400
What is kinetic molecular theory?
It explains what happens to matter when the kinetic energy of particle changes.

In everyday terminology, density can be described as the_______ of the particles that make up matter
a) spaciousness c) per unit volume
b) attractive nature d) crowdedness
What is per unit volume
500
What is the relationship between the amount of space between particles and the state of the matter?
What is the relationship between the amount of space between particles and the state of the matter is that they both can be in shapes of solid, liquid, and gas.
500
define heat
The energy that transferred from one material or object to another as a result of a difference in temperature or a change in state
500
How does the space between particles change as energy is added to them? How does the space change as energy is lost?
The space between particles when they are given energy is increased, and when energy levels drop, the space between particles decreases.
500
What are the four main points of kinetic molecular theory?
1. all matter is made up of particles(atoms and molecules)
2. there is empty space between particles
3. particles are constantly moving
4. energy makes particles move, the more energy the particles have, the faster they can move and the farther apart they can get
