在Year 10 AQA化学中，跨学科题目旨在评估你运用化学概念并结合数学、物理、生物和环境科学技能的能力。这些题目通常以真实情境呈现，要求你解读数据、进行计算，并用科学推理解释现象。
1. Chemistry and Mathematics: Mole Calculations in Solution | 化学与数学：溶液中的摩尔计算
Many exam questions ask you to convert between mass, moles and concentration using mathematical formulas. A typical task is: 'Calculate the concentration of 2.0 g of sodium hydroxide dissolved in 250 cm³ of water.'
许多考试题要求你运用数学公式在质量、摩尔和浓度之间进行转换。常见题型如：“计算将2.0 g氢氧化钠溶于250 cm³水中所得溶液的浓度。”
lume (dm³). Remember 250 cm³ = 0.250 dm³, so concentration = 0.050 / 0.250 = 0.20 mol/dm³.
要解答此题，你必须先求出NaOH的摩尔质量(40 g/mol)，计算摩尔数(2.0 / 40 = 0.050 mol)，然后浓度 = 摩尔数 / 体积(dm³)。记住250 cm³ = 0.250 dm³，因此浓度 = 0.050 / 0.250 = 0.20 mol/dm³。
n = m / M and c = n / V
Practice unit conversions and checking the correct number of significant figures – these mathematical details are often part of the mark scheme.
练习单位换算并检查有效数字的正确使用——这些数学细节往往是评分标准的一部分。
2. Chemistry and Physics: Energy Profile Diagrams and Bond Energies | 化学与物理：能量分布图与键能
Interdisciplinary tasks may require you to interpret an energy profile diagram and calculate the overall energy change using bond energies from a table. For example, when hydrogen reacts with chlorine to form hydrogen chloride, the bond breaking and making involve energy transfers.
跨学科任务可能会要求你解释能量分布图，并利用表格中的键能数据计算总能量变化。例如，氢与氯反应生成氯化氢时，键的断裂和形成涉及能量转移。
You might be given average bond energies: H–H = 436 kJ/mol, Cl–Cl = 243 kJ/mol, H– = 679 kJ) and energy released forming bonds (2 × 432 = 864 kJ). The overall change is 679 – 864 = –185 kJ, an exothermic reaction.
你可能会得到平均键能：H–H = 436 kJ/mol，Cl–Cl = 243 kJ/mol，H–Cl = 432 kJ/mol。反应为H₂ + Cl₂ → 2HCl。计算断裂键所需能量(436 + 243 = 679 kJ)和形成键释放的能量(2 × 432 = 864 kJ)。总变化为679 – 864 = –185 kJ，这是一个放热反应。
In an exam, you could also be asked to sketch the energy profile, labeling activation energy and ΔH. This blends physics concepts of energy conservation with chemical bonding.
在考试中，你可能还会被要求绘制能量分布草图，标出活化能和ΔH。这结合了物理的能量守恒概念与化学键合。
3. Chemistry and Biology: Fermentation and Enzyme Action | 化学与生物：发酵与酶的作用
carbon dioxide using enzymes in yeast. The balanced equation is: C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂.
发酵是一个生物过程，利用酵母中的酶将糖转化为乙醇和二氧化碳。其化学方程式为：C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂。
Questions may ask about the optimum temperature for the enzymes (around 35°C) and why the reaction stops if the temperature is too high (enzymes denature). You need to link the chemical equation with biological conditions.
题目可能会询问酶的最适温度(约35°C)，以及如果温度过高反应为何停止(酶失活)。你需要将化学方程式与生物条件联系起来。
Data analysis might include a graph of rate of CO₂ production against temperature; you would then explain the trend using knowledge of enzyme kinetics and chemical reaction rates.
数据分析可能包括CO₂产生速率随温度变化的曲线图；随后你需要运用酶动力学和化学反应速率的知识解释这个变化趋势。
4. Chemistry and Environmental Science: Greenhouse Gases and the Carbon Cycle | 化学与环境科学：温室气体与碳循环
Exam questions often combine the chemical properties of greenhouse gases such as CO₂ and methane with their environmental impact. You should know that CO₂ absorbs infrared radiation leading to global warming.
考试题经常将二氧化碳和甲烷等温室气体的化学性质与其环境影响结合起来。你应当知道CO₂吸收红外辐射，导致全球变暖。
uels. The chemical equation for complete combustion of methane is: CH₄ + 2O₂ → CO₂ + 2H₂O.
你可能需要解读大气中CO₂浓度随时间变化的数据(基林曲线)，并将其与化石燃料的燃烧联系起来。甲烷完全燃烧的化学方程式为：CH₄ + 2O₂ → CO₂ + 2H₂O。
O₂) and respiration equations, relating them to biomass and energy transfer in ecosystems.
一道跨学科题目也可以讨论碳循环，要求你配平光合作用(6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂)和呼吸作用的方程式，并将其与生态系统中的生物量和能量转移联系起来。
5. Chemistry and Geology: Extraction of Aluminium from Bauxite | 化学与地质：从铝土矿中提取铝
Aluminium extraction involves the electrolysis of aluminium oxide dissolved in molten cryolite. This process links chemistry with geology because the ore bauxite is mined from the earth's crust.
铝的提取涉及电解溶解在熔融冰晶石中的氧化铝。这一过程将化学与地质学联系起来，因为铝土矿是从地壳中开采出来的。
4e⁻. The carbon anodes are gradually burnt away due to reaction with the oxygen produced.
你需要写出电极半反应式：阴极，Al³⁺ + 3e⁻ → Al；阳极，2O²⁻ → O₂ + 4e⁻。碳阳极由于与生成的氧气反应而逐渐消耗。
Data interpretation might involve the huge energy consumption and how cryolite reduces the operating temperature from over 2000°C to about 950°C, saving costs. This ties chemistry to industrial and geological resource management.
数据解读可能涉及巨大的能量消耗，以及冰晶石如何将操作温度从2000°C以上降至约950°C从而节省成本。这便将化学与工业和地质资源管理联系起来。
