Understanding the Process of Diffusion of Gases
Learn about the diffusion of gases in this GCSE Science Revision video
00:00:01 Learn about the diffusion of gases in this GCSE Science Revision video. Invisible gases spread out randomly in all directions, and you can observe this process using bromine gas in the lab.
Diffusion is the process by which gases spread out and mix with one another.
Gases diffuse due to the random movement of their particles.
This process can be observed using bromine and air in a lab.
00:01:03 The video explains the process of diffusion of gases and demonstrates how gases diffuse at different rates in different conditions.
🔬 Diffusion of gases
⏰ Diffusion is slower in vacuum conditions
⚗️ Setup can be used to compare diffusion rates of different gases
00:02:09 This video explores the diffusion of gases, comparing the rates of different gases using cotton wool and observing their approach towards each other.
🔬 Diffusion is the process by which gases spread out.
⚖️ Heavier gases diffuse more slowly than lighter gases.
🌫️ When ammonia and hydrogen chloride gases meet, they form a white cloud of ammonium chloride.
00:03:13 This video explains the diffusion of gases, using the example of ammonium chloride. It discusses how to monitor the progress of gases and why ammonia travels faster.
🔍 The diffusion of gases can be observed using indicator paper.
🏃♂️ Ammonia gas travels faster than hydrogen chloride gas.
❓ The reason for ammonia traveling faster needs further investigation.
