nature of matter Flashcards
what are the natures of solid ( shape, volume, ease of flow, compressiblity, 3d state of diagram)
-fixed shape,
-fixed volume
-does not flow
-not compressible
what are the natures of liquid ( shape, volume, ease of flow, compressiblity, 3d state of diagram)
-no fixed shape, takes shape of container
-fixed volume
-flow
-not compressible
what are the natures of gas ( shape, volume, ease of flow, compressiblity, 3d state of diagram)
-no fixed shape, take shape of container
-no fixed volume
-flow
-compressible
what are the arrangment of particles for solid liquid and gas
solid: fixed regular pattern, packed closely tgt
liquid: no fixed positions, no regular pattern, slightly further apart than solid, closer than gas
gas: no fixed positions, no regular pattern, particles are far apart
motion of particles (solid, liquid, gas)
solids: particles vibrate abt fixed positions
liquids: particles slide past each other, freely and changes positions
gas: particles move freely & randomly, at high speeds occupying any available space
forces of attraction btwn particles (solid, liquid, gas)
solid : strong forces of attraction
liquid: weaker than solid, stronger than gas
gas: very weak forces of attraction
3d drawing of particles (liquid, solid, gas)
solid: same size, touch each other, no overlap, regular pattern
liquid: same size, touch, overlap, irregular pattern
gas: same size, at least 5, not touch, no overlap, irregular pattern
what happens when a ball is heated?
particles GAIN energy and vibrate MORE vigorously abt their FIXED positions, dist btwn particles INCREASE, volume of ball INCREASE, thus it EXPANDS
what happens when a ball is cooled
particles LOSE energy and vibrate LESS vigorously abt their FIXED positions, dist btwn particles DECREASE, causing volume of ball to DECREASE, thus it CONTRACTS
what happens to the number & size of particles during expansion & contraction
they dont change
