States of Matter
The state of matter with a definite volume but no definite shape.
What is a liquid?
The phase change from a solid to a liquid.
What is melting?
The process where a liquid turns into a gas throughout the entire volume of the liquid, producing bubbles.
What is boiling?
The phase change from a liquid to a solid.
What is freezing?
Ice turning into water on a warm day is an example of this phase change.
What is melting?
The state of matter where particles are spread far apart and move randomly and quickly.
What is a gas?
During melting, heat energy is being absorbed by the substance, making this kind of process.
What is endothermic?
The specific temperature at which a liquid turns into a gas throughout its volume.
What is the boiling point?
Both freezing and condensation are exothermic processes because heat energy is being done this.
What is released (or removed)?
Water droplets forming on the outside of a cold soda can.
What is condensation?
This fourth state of matter is made up of charged particles, like in a fluorescent light bulb or the Sun.
What is plasma?
The specific temperature at which a solid substance turns into a liquid.
What is the melting point?
The phase change from a liquid to a gas that occurs only at the surface of the liquid.
What is evaporation?
The phase change from a gas to a liquid, often seen as water droplets on a cold glass.
What is condensation?
Clothes drying on a clothesline is caused by this.
What is evaporation?
This term describes the energy of motion that determines how fast particles are moving in a substance.
What is kinetic energy?
This is the specific amount of energy needed to melt a unit mass of a substance at its melting point.
What is the Heat of Fusion?
On a high mountain, the lower atmospheric pressure causes water's boiling point to do this.
What is decrease (or lower)?
Water boils at this temperature in Celsius.
What is 100°C?
Frost forming on grass on a cold morning.
What is deposition?
The state of matter where particles are tightly packed and vibrate in fixed positions.
What is a solid?
Adding salt to ice water causes the melting point of the ice to do this.
What is decrease (or lower)?
This is the reason why a burn from steam is often more severe than a burn from boiling water.
What is latent heat or the Heat of Vaporization?
Phase changes where particles lose energy.
What are freezing, condensation, and deposition?
Dry ice turning straight into carbon dioxide gas.
What is sublimation?
