Questions using particle model
Problem 1
- Solid particles are completely motionless.
- particle model: A simplified explanation of matter using tiny moving constituents and their arrangement.
- A gas has no mass because it is invisible.
- One illustrative result establishes every real condition and needs no further evidence.
Answer and explanation
particle model: A simplified explanation of matter using tiny moving constituents and their arrangement.
A simplified explanation of matter using tiny moving constituents and their arrangement. Melting in the closed sample changes arrangement while retaining its 50 g of water. The open dish loses 6 g from the measured liquid; evaporation is a possible pathway into the air. The water has not been destroyed. Without further records, the mass loss alone does not exclude a spill or specify the evaporation rate over a particular time.
Problem 2
- A gas has no mass because it is invisible.
- Solid particles are completely motionless.
- evaporation: A change from liquid to gas at a surface, possible below boiling.
- One illustrative result establishes every real condition and needs no further evidence.
Answer and explanation
evaporation: A change from liquid to gas at a surface, possible below boiling.
A change from liquid to gas at a surface, possible below boiling. Melting in the closed sample changes arrangement while retaining its 50 g of water. The open dish loses 6 g from the measured liquid; evaporation is a possible pathway into the air. The water has not been destroyed. Without further records, the mass loss alone does not exclude a spill or specify the evaporation rate over a particular time.
Problem 3
- Every classroom model reproduces reality exactly.
- Solid particles are completely motionless.
- A gas has no mass because it is invisible.
