On a cool (4.0$^\circ$C) Saturday morning, a pilot fills the fuel tanks of her Pitts S-2C (a two-seat aerobatic airplane) to their full capacity of 106.0 L. Before flying on Sunday morning, when the temperature is again 4.0$^\circ$C, she checks the fuel level and finds only 103.4 L of gasoline in the aluminum tanks. She realizes that it was hot on Saturday afternoon and that thermal expansion of the gasoline caused the missing fuel to empty out of the tank's vent. (a) What was the maximum temperature (in $^\circ$C) of the fuel and the tank on Saturday afternoon? The coefficient of volume expansion of gasoline is $9.5 \times 10{^-}{^4} K{^-}{^1}$. (b) To have the maximum amount of fuel available for flight, when should the pilot have filled the fuel tanks?
