Question 13
Sofia and Marcus each measured 10 cm³ of dilute hydrochloric acid into a test tube and measured the temperature. Then they each added an identical piece of magnesium ribbon to their test tube of acid. When the reaction stopped, they each measured the temperature again.
| Learner | Start temperature / °C | End temperature / °C |
|---|---:|---:|
| Sofia | 18 | 42 |
| Marcus | 21 | 45 |
Sofia and Marcus wondered how they could produce a higher temperature change. Their ideas included adding more magnesium, using a different metal and using a different acid.
Write each of these three ideas as a scientific question to be investigated.
