Worked Solution & Example Answer:A student investigates what happens when she heats a beaker of water - OCR Gateway - GCSE Physics - Question 10 - 2020 - Paper 1
Step 1
Which row in the table describes what could happen when the water is heated?
Answer
To determine which row could occur when water is heated, we need to analyze the impacts of heating on water:
- The Temperature Increases: Heating water will generally result in an increase in temperature.
- The State Changes: As the water heats, it may change from solid (ice) to liquid (water), and eventually from liquid to gas (steam). This means a state change can occur depending on the initial temperature of the water being heated.
- The Energy Stored in the Water Changes: Heating water increases the energy within it, translating to higher thermal energy.
Based on this analysis, we see that Row A ( The temperature increases ✔, The state changes ✔, The energy stored in the water changes ✔) accurately represents all potential changes. Therefore, the correct answer is A.
