## Homework Statement

a steel tank is 70 litres,full of petrol. If a temperature is change from 20

^{o}C to 35

^{o}, find the increased volume of petrol that overflows

(

**β**= 950 x 10

_{steel}^{-6})

**β**= 36 x 10

_{petrol}^{-6})

## Homework Equations

Δv=

**β**v

_{0}ΔT

## The Attempt at a Solution

I know that both the steel tank and petrol will be increased by the heat and my equation is

change in volume of petrol - change in volume of steel = volume of petrol that overflows

Δv

_{petrol}- Δv

_{steel}= v

_{f}

and I got stuck with the volume of the tank :/
