GCSE Chemistry - Fractional Distillation - Crude Oil | Hydrocarbons (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. Crude Oil How crude oil is formed from the remains of ancient biomass. Its composition as a mixture of hydrocarbons, primarily alkanes. Why crude oil is classified as a finite, non-renewable resource. 2. Fractional Distillation The principle of separating a mixture based on different boiling points. The function of a fractionating column with its temperature gradient. Step-by-step explanation of how crude oil is separated into different fractions. 3. Fractions and their Properties The relationship between the length of hydrocarbon chains and their boiling points. Examples of different fractions, including bitumen, heavy fuel oil, diesel, kerosene, petrol, and LPG. The uses of various fractions, from road surfacing to fuel for cars and aeroplanes. The concept of petrochemicals and their use as feedstock. ** CHAPTERS ** 0:00 Introduction 0:19 What is Crude Oil? 1:57 What is Fractional Distillation? 2:25 The Process of Fractional Distillation 4:05 Properties and Uses of Fractions ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Chemistry #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE #IB #AP
