1. What is the volume of a quantity of a gas at 172 Celcius, if its volume is 262 mL at -25 Celcius? The pressure remains constant. 2. What is the pressure, in inches of mercury, of a gas that originally had a volume of 252 mL, under a pressure of 0.834 atmosphere and a temperature of 45 Celcius if the volume is reduced to 16 ...continues
Plot the Maxwell distributions for CO2, N2, and He at 298K in the velocity range of 0 to 2500 m/s. Label each curve appropriately. What temp. would you have to change the CO2 to cause it to have the same mean velocity as the He at 298K? What fraction of the N2 molecules are in the velocity range 500 to 1000 m/s? What is th ...continues
