Calculate heat absorbed by solution
In a Melbourne school calorimetry practical, \(75\,\text{g}\) of water warms by \(7^{\circ}\text{C}\). Use \(q=mc\Delta T\), with \(c=4.18\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}\), and give \(q\) in kJ. Use the energy diagram labels first, then calculate carefully. Enter the answer and choose the interpretation that matches the chemistry.
Worked practice: chemistry evidence and answer
Use the chemical evidence first, then enter the result and interpretation that match it.
Write a full answer
Now write the response in full, in your own words — this is what the exam asks for. The AI marks it on the same moves you built above (focus, evidence, technique, judgement) and gives feedback on reasoning, evidence, and expression.
