6. Correct the following misconceptions about the nature of matter:
a. There is air between the tiny discrete particles in a substance.
b. Particles of a substance in different states have different shapes and sizes.
c.When ice melts, the particles of ice change into other types of particles.
d. When a solid is heated, its particles melt and change into a liquid.
e. When a substance is heated, its particles expand and increase in size.
f. Particles of a liquid move only when the liquid is shaken.
g. Particles of a solid do not move.
Answers
a.
No there is no such air between the tiny discrete particle as a single molecule of "air" is too big to fit in between those tiny discrete particle.
b.
No the size of the each particle remains as same it was before changeing the state of the substance.
Substance's state does and cannot effect the size of the particles.
c.
No. changing of state doest or cannot affect he particles,so when ice melts,it doesn't effect them.
d.
No it doesn't. when it melts just the bond between the particles gets loos..so they moves far away from each other.(Here particle means the atom of the substance)
e.
No it doesn't effect the size,their inter molecular bonds get loosen enought to move far away from eachother...and the expansion happens.
f.
Basic or prime particles do not move,only the molecules of the liquid moves.
g.
it's right.
Answer:
g is not right
Explanation:
particles of solid do move but they only vibrate and spin around their fixed positions.
