Misconception of heat and temperature Among physics students
Type: Empirical
Data collection method: Test
Number of subjects, range: Other or unknown
Grade and age of subjects: 9th-12 grade — 15-18 years
Conceptions of temperature
- Temperature is the “intensity” of heat.
- Skin or touch can determine temperature.
- Perceptions of hot and cold are unrelated to energy transfer.
- When temperature at boiling remains constant, something is “wrong.”
- Boiling point is the maximum temperature a substance can reach.A cold body contains no heat.
- The temperature of an object depends on its size.
- There is no limit on the lowest temperature.
Thermal properties” of materials.
- Temperature is a property of a particular material or object.
- Metal has the ability to attract, hold, intensify or absorb heat and cold.
- Objects that readily become warm do not readily become cold.
- Different materials hold the same amount of heat.
- The boiling point of water is 100°C (only).
- Ice is at 0°C and/or cannot change temperature.
- Water cannot be at 0°C.
- Steam is more than 100°C.
- Materials like wool have the ability to warm things up.
- Some materials are difficult to heat: they are more resistant to heating.
- Bubbles mean boiling.
- The bubbles in boiling water contain “air,” “oxygen,” or “nothing.” 12.
- It starts to melt at 420oC 29
