Question

whose rate of diffusion is higher-
liquid or gas?


Give prove to your answer along with an activity.
Explain that also.​

Answer 1

liquid is the rate of diffusion in higher

Answer 2

Rate of diffusion is higher in gases than liquids.

But why ??

• Intermolecular forces inbetween gas molecules is much lesser than in liquids.

• Intermolecular distance between gases is much greater than in liquids.

• These factors make gaseous diffusion much faster.

____________________________

Activity:

Aim:

• To prove that gas diffuse faster than liquids.

Materials required:

• 2 Cuboidal glass box (leak-proof)
• Liquid ink (of any colour)
• Perfumes (gas pressurized in cylinders)
• Water

Experiment:

• Take the cuboidal boxes and fill it with water upto the brim.

• In one box, put a few drops of ink.

• In the other box, press the perfume tap and let a small amout of gas into the water filled box.

Observation:

• Gases (in the form of bubbles) diffuse much faster in the bulk of the liquid.

• Whereas, the ink (liquid) will diffuse much slower.

Inference:

• Gases diffuse faster than liquids.
