Question 9.7:
A table shows voltage (V) and current (I) readings for a resistor at 0°C and 100°C. Explain why the resistance increased at higher temperature.
Model answer:
At higher temperatures, metal ions in the resistor vibrate more vigorously. This increases collisions with free electrons, hence increasing resistance. This is consistent with the positive temperature coefficient of metals. new mastering science workbook 2b answer chapter 9

⚠️ Avoid shady “free PDF” sites. They often contain wrong answers (e.g., mixing up current and voltage formulas), which will hurt your exam prep.
| Question | Typical Correct Answer | Explanation | |----------|----------------------|--------------| | 1. Which device measures potential difference? | B) Voltmeter | Ammeter measures current, ohmmeter measures resistance, galvanometer detects small currents. | | 2. In a series circuit with two identical bulbs, if one bulb blows, the other: | C) Goes out | The circuit is broken; current cannot flow. | | 3. Which material is best for a conductor? | A) Copper | Lowest resistivity among common metals (silver is better but expensive). | ⚠️ Avoid shady “free PDF” sites
