Matter Flashcards
What is MATTER
A substance that has mass and occupies space
Name the three states of matter
Solid,Liquid, and Gas
State the characteristics of Solid
-Packed closely together in fixed and regular pattern
-Has very small space
-Fibrate at fixed position and has low kinetic energy
State the characteristics of Liquid
-Still packed closely but not as close at Solid
-Moderate space
-Not arranged in a pattern
-Move freely and collide with each other
-more kinetic energy
State the characteristics of Gas
-Far apart from each other
-Large space
-Move freely and randomly in all directions and has more kinetic energy
What about Shape,Volume,Density and Compressibility of Solid
Fixed Shape,Fixed Volume,High density(large number of particles), and cannot be compressed
What about Shape,Volume,Density and Compressibility of Liquid
No fixed shape (takes shape of container) , has fixed volume (arranged closely),moderate density(similar number of particles), Cannot be compressed
What about Shape,Volume,Density and Compressibility of Gas
No fixed shape,No fixed volume,Very low density(small number of particles), can be compressed
What is Sublimation where heat is absorbed?
Sublimation in absorbing heat,the solid changes into gas directy without melting. Solid-Gas
What is melting?
Melting is when heat energy is absorbed.The heat energy is then converted to kinetic energy and the particles begin to vibrate faster. Solid-Liquid
What is boiling.
Boiling is when heat energy is absorbed.The heat energy begins to move faster as the temperature rises. Liquid-Gas
What is Condensation?
Heat is released,the particles lose kinetic energy and begin to move slower.When the temperature is equal to or lower than the boiling point,the gas will turn into liquid. Gas-Liquid
What is Freezing?
Heat is released,the particles lose kinetic energy and begin to move slower and closer to each other.When the particles no longer have energy to move freely,the particles will settle in a fied postition. Liquid-Solid
What is Sublimation where heat is released?
Sublimation where heat is released is a process of when the gas is cooled,the gas particles lose energy and move more slowly
What if Diffusion
Diffusion is a movement of particles from a region of high concentration to a region of low concentration
