Fuel systems of modern cars are designed so thermal expansion of gasoline doesn't result in wasteful and polluting fuel spills. As an engineer, you're asked to specify the size of an expansion tank that will handle this overflow. You know that gasoline comes from its underground tank at 10 degees celcius, and your tank must handle the expansion of a full 55 L gas tank when the gas reaches a hot summer day's temperature of 34 degrees celcius.
How large an expansion tank do you specify?
