in some case we take y=-g but in some case we take y=g... why???
One mole of an ideal gas at 0°C is compressed adiabatically reversibly to a pressure of 20 times its initial pressure. Evaluate the final temperature.(γ=1.4)
Factors which are affect velocity of sound in gaseous medium is (1) Effect of density (2) Effect of pressure (3) Effect of temperature : (4) Effect of humidity
