States of Matter
A state of matter that has a fixed shape and fixed volume.
Solid
The change when a solid turns directly into a gas.
Sublimation
The movement of thermal energy from warmer particles to cooler particles.
Heat Transfer
A word that describes anything related to heat or temperature.
Thermal
The heat transfer method used when a metal spoon gets hot in soup.
Conduction
A state of matter that has a fixed volume but takes the shape of its container.
Liquid
The change when a gas turns directly into a solid.
Desublimation
Heat transfer that happens through direct contact between particles.
Conduction
The total energy of particle motion in a substance.
Thermal energy
The heat transfer method that causes warm air to rise and cool air to sink.
Convection
A state of matter that spreads out to fill its container completely.
Gas
This phase change releases energy to the surroundings.
Exothermic change
Heat transfer caused by the movement of fluids like liquids or gases.
convection
This kind of change absorbs heat from the surroundings.
Endothermic change
The phase change that forms frost on a cold window.
Desublimation
The change of state when a solid turns into a liquid.
Melting
This phase change absorbs energy from the surroundings.
Endothermic Change
Heat transfer that can travel through empty space.
Radiation
This kind of change releases heat into the surroundings.
Exothermic change
The phase change that causes ice to disappear on a warm day.
Melting
The change of state when a liquid turns into a solid.
Freezing
This change happens when water vapor forms liquid droplets.
Condensation
This type of heat transfer explains why the Sun warms Earth.
Radiation
When particles move faster, this form of energy increases.
Thermal Energy
When hand warmers give off heat during a reaction, the process is described as this.
Exothermic reaction
