Match the state of matter to its definition.

• Bose-Einstein Condensates

• Most common form of matter in universe with positive and negative particles

• Plasma

• Atoms that exist at extremely low temperatures - "super atom"

• Gas

• Particles in this state move so much that there is no definite shape or volume.

• Liquid

• Definite volume, but shape is based on container

• Solid

• Particles are held together in a rigid structure.

What happens to particles when they gain or lose thermal energy?

• Particles become heavier and sink when gaining thermal energy.
• Particles remain stationary regardless of thermal energy changes.
• Particles undergo a state change from solid to liquid to gas when gaining thermal energy.

• Particles dissolve into gas when losing thermal energy.

How is evaporation different from boiling?

• Evaporation occurs only at high temperatures; boiling happens at low temperatures.
• Boiling requires a specific pressure; evaporation does not depend on pressure.

• Evaporation is surface-level and occurs at any temperature; boiling occurs throughout the liquid at a specific temperature.
• Boiling is a surface phenomenon, while evaporation occurs throughout the liquid.

What is a heating curve?

• A heating curve is a method for cooling substances quickly.
• A heating curve is a graph that depicts the temperature changes of a substance as it is heated, including phase transitions.
• A heating curve is a type of thermometer used for measuring temperature.
• A heating curve shows the pressure changes of a gas over time.
