The Particle Party
This state of matter has a definite shape and a definite volume.
What is a solid?
The process of a liquid turning into a gas at the surface of the liquid.
What is evaporation?
Temperature is a measurement of the average _ energy of the particles in a substance.
What is kinetic energy?
This property is defined as the force exerted by gas particles colliding with the walls of their container.
What is pressure?
The "fourth state of matter" consists of ionized gas and is found in stars and neon signs.
What is plasma?
In this state, particles are close together but can slide past one another, allowing it to flow.
What is a liquid?
This occurs when a solid turns directly into a gas without becoming a liquid first.
What is sublimatioN?
This is the theoretical temperature at which all particle motion stops.
What is absolute zero?
According to Boyle's law, if you decrease the volume of a gas, this happens to the pressure.
What is increases?
Water is unique because its solid state is _ dense than its liquid state.
What is less?
This theory that all matter is made up of tiny particles that are constantly in motion.
What is the kinetic theory?
This is the specific temperature at which a liquid turns into a solid.
What is the freezing point?
A process that absorbs heat energy from its surroundings is called this.
What is endothermic?
Charles's law states that the volume of a gas is directly proportional to this, provided pressure is constant.
What is temperature?
This type of solid has no long-range order or repeating pattern in its unit cells.
What is an amorphous solid?
Gases are easily compressed because of this specific feature of their particle arrangement.
What is the large amount of empty space between particles?
During a phase change, the temperature of a substance does this.
What is stays the same?
On a heating curve, these flat, horizontal sections represent what is happening.
What are phase changes?
This describes the movement of gas particles from an area of high concentration to an area of low concentration.
What is diffusion?
This specific temperature and pressure point is where a substance can exist as a solid, liquid, and gas simultaneously.
What is the triple point?
These are the attractive forces between molecules that determine whether a substance is a solid, liquid, or gas at room temperature?
What are the intermolecular forces?
The phase change where a gas turns directly into a solid, such as frost forming on a window.
What is deposition?
This is the amount of energy required to change substance from a solid to a liquid at its melting point.
What is the heat of fusion?
These is the SI unit for pressure.
What is the Pascal?
What is the most common state of matter in the universe?
