📚 Year 7 CAIE Physics: Interdisciplinary Integrated Question Training | 剑桥初中物理：跨学科综合题型训练
In Year 7 CAIE Physics, you will often meet questions that link physics with other subjects such as mathematics, chemistry, biology and geography. These interdisciplinary questions test your ability to apply knowledge across boundaries and are a key part of the Cambridge Lower Secondary Science assessment. This article provides targeted training to help you master these integrated problem types.
在剑桥初中物理 Year 7 的学习中，你经常会遇到将物理与数学、化学、生物、地理等其他学科结合起来的题目。这些跨学科题目考查你综合运用知识的能力，也是剑桥初中科学测评的重要部分。本文将为你提供针对性的训练，帮助你掌握这些综合题型。
1. What Are Interdisciplinary Questions? | 什么是跨学科题目？
Interdisciplinary questions require you to combine knowledge from at least two different subject areas. For example, a physics problem might ask you to calculate the speed of a runner, but the data might be presented in a graph (mathematics) or linked to the energy in food (biology, chemistry).
跨学科题目要求你综合运用至少两个不同学科领域的知识。例如，一道物理题可能让你计算跑步者的速度，但数据可能以图表形式呈现（数学），或者与食物中的能量（生物、化学）相关联。
Common interdisciplinary links in Year 7 Physics include: using formulas and graphs (Maths), explaining changes of state (Chemistry), understanding forces in the human body (Biology), and interpreting earthquake data (Geography).
Year 7 物理中常见的跨学科联系包括：使用公式和图表（数学）、解释物态变化（化学）、理解人体内的力（生物）、以及解读地震数据（地理）。
2. Physics and Mathematics: Speed, Distance and Time | 物理与数学：速度、距离与时间
A typical interdisciplinary question: 'A car travels 120 km in 2 hours and 30 minutes. Calculate its average speed in km/h and in m/s.'
典型的跨学科题目：“一辆汽车行驶120千米用了2小时30分钟。计算它的平均速度，以千米每小时和米每秒为单位。”
m/s (÷3.6). Solution: time = 2.5 h, speed = 120 ÷ 2.5 = 48 km/h. Then 48 ÷ 3.6 ≈ 13.3 m/s.
所需物理知识：速度 = 距离 ÷ 时间。数学技能：单位换算，时间以十进制小时表示，以及将千米每小时转换为米每秒（除以3.6）。解答：时间 = 2.5 小时，速度 = 120 ÷ 2.5 = 48 km/h。然后 48 ÷ 3.6 ≈ 13.3 m/s。
Be careful: many students forget to convert minutes to hours correctly. Always check that units match.
注意：许多学生忘记将分钟正确转换为小时。务必检查单位是否匹配。
3. Chemistry in Physics: Heating Curves and States | 化学中的物理：加热曲线与物态
When you heat a solid, its temperature rises until it melts. The heating curve combines physics (heat transfer, temperature) and chemistry (changes of state, particle theory). You might be asked to interpret a graph showing temperature vs. time for ice turning to water and then steam
