GCSE Physics (9-1) - GCSE Physics - Pressure & Volume | pV = Constant Equation (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. The relationship between pressure and volume in gases. * A recap of how pressure is created by gas particles colliding with container walls. * An overview of the factors that affect gas pressure: temperature, number of particles, and volume. 2. Boyle's Law: The inverse relationship between pressure and volume. * Explanation that for a fixed mass of gas at a constant temperature, pressure and volume are inversely related. * Introduction to the equation pV = constant. 3. Using the pressure-volume equation in calculations. * A worked example calculating the new pressure of a gas after its volume is compressed. * A worked example calculating the pressure of atmospheric air when compressed into a smaller gas cylinder. *** EXAM BOARD SPECIFIC INFO *** AQA - Separate (triple) science only IGCSE Edexcel - Everything is relevant to your course!
