Question

A 60 litre steel gasoline tank is full of gas, so that both the tank and the gasoline

have a temperature of 15 °C. The amount of gasoline has been spilled by the time
they warm up to 35 °C will be:
(A) 50.2 litre
(B) 1.10 litre
(D) None
(C) 3.26 litre

Answer 1

To solve this problem, we need to use the coefficient of thermal expansion for gasoline, which tells us how much the volume of gasoline will increase as its temperature increases. The coefficient of thermal expansion for gasoline is approximately 950 x 10^-6 /°C.

Using this information, we can calculate the increase in volume of gasoline as it warms up from 15°C to 35°C:

ΔV = V * α * ΔT

where V is the initial volume of gasoline (60 L), α is the coefficient of thermal expansion for gasoline (950 x 10^-6 /°C), and ΔT is the change in temperature (20°C).

ΔV = 60 * 950 x 10^-6 * 20

ΔV = 0.114 L

Therefore, the amount of gasoline spilled as it warms up from 15°C to 35°C is:

60 L - 0.114 L = 59.886 L

Step-by-step explanation:

So the answer is (A) 50.2 litre.
