State Changes Flashcards
What is the process from solid state going to liquid state?
Melting
What is the process from liquid going to solid state?
Freezing
What is the process from liquid going to gas state?
Evaporation
What is the process from gas going to liquid state?
Condensation
What is the process from gas to solid-state?
Deposition
What is the process from solid to gas state?
Sublimation
What is dry ice made of?
Carbon dioxide
What is a triple point?
Triple point is where solid, liquid, and gas states are all found at the same time and is unique for each material.
What is the most important thing that determines whether a particle is in the solid, liquid, or gas state?
Depends on the movement of the particles
What happen when you place a coin on dry ice?
The coin will vibrate and make a high-pitched screeching sound, but it will not make crystals. dry ice sublimates to gas at a very low temperature. The gas from the ice will push on the coin and the coin pushes back on the ice resulting in vibrations.
What happens when you put dry ice into water?
It’s sublimates into gas
What is kinetic energy?
Kinetic energy is energy that an object has due to its motion.
What is thermal energy?
Thermal energy of a substance depends on temperature
What is potential energy?
Potential energy is stored energy due to the interactions between particles or objects
