1. ### 2.75 m3 of a gas initially at STP is placed under a pressure of 3.62 atm ,the temperature of the gas rises to 37.1 ∘C.What is the volume?

T2 = 310.2°K T1 = 273.1°K P2 = 3.62*P1 Vf = Vi*[T2/T1]*[P1/P2] = 0.863 m³

Either there is a lot of extraneous data here, or I miss the point. A tube open at both ends has a fundamental wavelength equal to twice the distance between the ends, so here λ = 2 * 8cm = 0.16 m, so f = v / λ = 340m/s / 0.16m = 2125 Hz Hope this helps!
