# Diffusion coefﬁcient of gases in liquids

• MRG1373
Transport Phenomena by Bird, Stewart, and Lightfoot) In summary, the conversation was about the diffusion coefficient of gases in liquids and whether liquid-liquid models could be used for gas-liquid models. The book "THE PROPERTIES OF GASES AND LIQUIDS" by Bruce E. Poling was mentioned, but it did not directly mention the diffusion coefficient. A suggestion was made to check out the book "Transport Phenomena" by Bird, Stewart, and Lightfoot.

TL;DR Summary
diffusion coefﬁcient of gases in liquids
recently I'm looking for diffusion coefﬁcient of gases in liquids. I have read "THE PROPERTIES OF
GASES AND LIQUIDS" from Bruce E. Poling. but in this book it isn't directly mention what is diffusion coefﬁcient of gases in liquids. can we using liquid-liquid models for gas-liquid models?

Were you able to check out the book suggested by @Chestermiller ?

## 1. What is diffusion coefﬁcient of gases in liquids?

The diffusion coefﬁcient of gases in liquids is a measure of how easily a gas can move through a liquid. It is a physical property that describes the rate at which a gas will diffuse or spread out through a liquid.

## 2. How is the diffusion coefﬁcient of gases in liquids determined?

The diffusion coefﬁcient of gases in liquids is typically determined through experiments in a controlled environment. The rate of diffusion is measured and then the diffusion coefﬁcient is calculated using equations that take into account factors such as temperature, pressure, and the properties of the gas and liquid.

## 3. What factors affect the diffusion coefﬁcient of gases in liquids?

The diffusion coefﬁcient of gases in liquids can be affected by several factors including temperature, pressure, the properties of the gas and liquid, and the presence of other substances in the liquid that may interact with the gas.

## 4. Why is the diffusion coefﬁcient of gases in liquids important?

The diffusion coefﬁcient of gases in liquids is important in many scientific and industrial applications. It is used to understand and predict the behavior of gases in liquids, which is important in fields such as chemical engineering, environmental science, and materials science.

## 5. Can the diffusion coefﬁcient of gases in liquids be changed?

Yes, the diffusion coefﬁcient of gases in liquids can be changed by altering the conditions under which diffusion occurs. For example, increasing the temperature or pressure can increase the diffusion coefﬁcient, while adding other substances to the liquid can decrease it.
