1. The problem statement, all variables and given/known data The density of a sample of air is 1.211 kg/m3, and the bulk modulus is 1.42 · 105 N/m2. a) Find the speed of sound in the air sample. b)Find the temperature of the air sample. Give answer in °C. 2. Relevant equations 3. The attempt at a solution I found the part a it's It's 342.43 m/s But i find b wrong everytime.What i use is; sqrt[(1.4 x r x T)/M] = speed But maybe i know the some values wrong? Help please.
