Application +4 | -1

Suppose that one early morning when the temperature is

10^{\circ} \mathrm{C}

, a driver of an automobile gets his gasoline tank which is made of steel, filled with 75 litre of gasoline, which is also at

10^{\circ} \mathrm{C}

. During the day, the temperature rises to

30^{\circ} \mathrm{C}

. How much gasoline will overflow? Given

\alpha

for steel

=1.2 \times 10^{-5}{ }^{\circ} \mathrm{C}^{-1}

and

\gamma

for gasoline

=9.5 \times 10^{-4}{ }^{\circ} \mathrm{C}^{-1}

View answer and explanation

Correct option: A

1.37 litre

Option A (1.37 litre) is correct because it is calculated by finding the difference between the change in volume of gasoline and the change in volume of the steel tank due to thermal expansion.
