* Gasoline is a mixture: It's not a pure substance, but a blend of hydrocarbons with varying chain lengths and compositions. Each component has its own coefficient of thermal expansion.
* Composition varies: The specific blend of gasoline varies depending on location, season, and refinery practices. This further affects the overall expansion behavior.
* Temperature dependency: The coefficient of thermal expansion itself changes with temperature.
Instead of a single value, we can look at typical ranges:
* Approximate Volume Expansion: Gasoline expands roughly 0.1% for every 1°C (or 1.8°F) temperature increase. This means if you have 100 liters of gasoline at 20°C and raise the temperature to 30°C, the volume would increase by about 1 liter.
* Typical Coefficient: While hard to pin down a specific number, sources often cite values around 1.0 x 10^-3 / °C. However, remember this is a general approximation.
Important Note:
* The expansion of gasoline is a significant factor in fuel tank design and safety considerations.
* It's why filling your tank to the brim on a hot day can lead to spillage.
If you need a precise value for a specific application, you'll need to consult with a fuel expert or refer to the technical specifications of the gasoline in question.
