Exploring misconceptions about the characteristics of solid, liquid and gas among junior high school students in Kampot province, Cambodia
Type: Empirical
Data collection method: Interview, Test
Number of subjects, range: Large — 31 or more
Grade and age of subjects: 6th-8th grade — 12-14 years
Physical characteristics solid, liquid, and gas
- When the temperature decreases, gas particles shrink.
- When the temperature decreases, the number of gas particles decreases.
- Gas particles move everywhere because the wind blows them and they are light.
- When compressing, the number of gas particle decrease.
- When gas is compressed, particles shrink.
- When gas is compressed, particles stick together.
- When gas is compressed, particles are all pushed to the end of the syringe.
- Particles escape to make changes in the volume of liquid.
- Liquid particles move freely to make changes in volume.
- Liquid particles move freely to make changes in volume.
- There is no space between particles.
- Heavier ink particle sinks to the bottom of the tube.
- Particles of liquid cannot move.
- Size and number of particles decrease when a solid is melted.
- Size of solid particles decreases when solid is pressed.
Partial characteristics of solid, liquid, and gas
- Solid must be hard.
- Substances which can flow are liquid.
- Substances that are powdery are considered as liquids.
- Gas has no mass.
- Hot air and cold air are weightless.
- Hot air is heavier than cold air.
- Liquid weight more than gas.
- Water vapor is weightless.
- All liquids must be watery.
- All substances can be poured are liquid.
