**Volumetric expansion Kelvin required???**

## Homework Statement

Suppose that the steel gas tank in your car is completely filled when the temperature is 11.5 °C. How many gallons will spill out of the 20.9- gallon tank when the temperature rises to 37.6 °C?

## Homework Equations

βgasoline = 950 x10-6

ΔV = β(V0)ΔT

## The Attempt at a Solution

ok so this rele seemed like a plug and jug question to me and i just cant figure out where i went wrong. This is what I did, my only questions are where did i go wrong or maybe are the temperatures supposed to be in Kelvins or would Celsius work to?

(950*10^-6)*(20.9)*(26.1)

why isnt this right?

Thanks yall
