Expansion Ratio Calculator

Formula

The formula to calculate the Expansion Ratio (ER) is:

\[ \text{ER} = \frac{V_f}{V_i} \]

Where:

\(\text{ER}\) is the expansion ratio
\(V_f\) is the final volume
\(V_i\) is the initial volume

What is an Expansion Ratio?

The expansion ratio is a measure of how much a substance expands when it undergoes a phase change or a chemical reaction. It is the ratio of the final volume to the initial volume. This concept is commonly used in various fields such as thermodynamics, engineering, and material science to understand the behavior of substances under different conditions.

Example Calculation

Let's assume the following values:

Initial Volume (V_i) = 2 cubic units
Final Volume (V_f) = 10 cubic units

Using the formula to calculate the Expansion Ratio:

\[ \text{ER} = \frac{10}{2} = 5 \]

The Expansion Ratio is 5.
