A 1.94L balloon filled with gas is warmed from 268.9K to 311.2 K. What is the volume of the gas after it is heated?

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.

Which accounts for an increase in the temperature of a gas that is kept a constant volume
