However, from Fig. 7, it is observed that the excess molar volumes, V m E, is positive which can be explained by the predominance of expansion in volume, caused by the loss of dipolar association and difference in size and shape of component molecules, over contraction in volumes, due to the dipole-dipole and dipole-induced dipole interactions (Petek and Dolecek 1998).

Expert writing Tips
Best practice
When discussing physical substances or containers, use "expansion in volume" to accurately describe the increase in the three-dimensional space they occupy. For abstract quantities, consider alternatives like "increase in amount".
Common error
Avoid using "expansion in volume" when you actually mean an increase in number or quantity. Volume specifically refers to three-dimensional space, not abstract counts.

Ludwig's WRAP-UP
In summary, "expansion in volume" is a grammatically correct phrase that refers to an increase in three-dimensional space. Ludwig's analysis of real-world examples shows that it's most commonly used in scientific and news contexts. While the phrase is accurate, it's essential to use it when you mean the growth or increase in the physical volume. For general growth, or increase, you can choose alternative such as "increase in size" or "growth in size".

FAQs
How is "expansion in volume" used in scientific writing?
In scientific contexts, "expansion in volume" often describes physical processes such as the thermal expansion of materials or changes in cell size. For example, you might read about the "expansion in volume" of a gas as it heats up.
What's a simple way to describe an increase in size instead of saying "expansion in volume"?
For simpler language, you could use phrases like "increase in size" or "growth in size", depending on the context.
When is it more appropriate to use "increase in amount" rather than "expansion in volume"?
"Increase in amount" is better when referring to abstract quantities or data, while "expansion in volume" is specific to physical three-dimensional space. For example, an "increase in the amount of data" versus the "expansion in volume" of a container.
Is "expansion in volume" a formal or informal expression?
The phrase "expansion in volume" is generally considered neutral to formal. It is suitable for academic, scientific, or technical writing, but might be replaced with simpler alternatives in casual conversation.
