Phases of Matter
The phase of matter with no definite shape OR definite volume
What is a gas?
What is melting?
According to kinetic molecular theory, these make up all matter
What are small particles?
The formula to calculate Density
What is mass divided by volume?
The study of matter and its changes
What is chemistry?
The phase of matter in which particles have the least potential energy possible
What is a solid?
In this process vapor in the air becomes a liquid
What is condensation?
A description of atoms and molecules
Atoms are the smallest unit of matter, and molecules are groups of atoms bonded together.
The unit for density
What is g/mL or g/cm3 ?
An explanation of how particles in matter behave
What is kinetic molecular theory?
The phase of matter with the most thermal (kinetic plus potential) energy
What is a gas?
An increase in this can cause a change in state
What are kinetic and potential energy?
Or
What are particle attraction and particle motion?
The particle arangement in the different states of matter
Solid-closely packed and vibrating
Liquid-close but sliding past each other
Gas-far apart not attracted to each other
Calculate the Density
Mass: 12g
Volume 3cm3
What 4g/cm3
Anything that takes up space and has mass
What is matter?
The phase of matter a substance would end as after the process of condensation.
What is a liquid?
In this process a liquid becomes a gas
What is vaporization?
How energy relates to particle movement
What is as the energy increases, the particles move faster and further apart?
Calculate the density
Mass: 24g
Volume: 4cm3
What is 6 g/cm3
The amount of space occupied by an object
What is volume?
The phase of matter a substance will end up as at the end of the process of deposition
What is a solid?
In this process matter changes from a solid to a gas, skipping the liquid state
What is sublimation?
The Key components of the kinetic molecular theory
All matter is made of small particles, that are in constant motion, that move more with more energy
Calculate the density
Mass: 12g
Volume 60mL
What is 5 g/mL ?
A characteristic of matter that can be measured or described with numerical value
The key components of the kinetic molecular theory are the constant motion of particles, their interactions, and their kinetic energy.
