Question 23
Step 3: Half-fill a glass with cold water. Clean a piece of magnesium ribbon with sandpaper and then drop it into the water. What do you observe after two minutes?
Step 4: Repeat your experiment from step 3 but use a glass of hot water (around 50–60°C) instead. Describe how your observations are different from those in step 3.
Why do you think the hot water had the effect on the metal? (Hint: Think about the energy involved.)
