solve question 1 and 2

1.1. Use the ideal gas equation of state to estimate the molar volume in m3/mol and the density of air in kg/m3 at 40C. And a gauge pressure of 3.0atm. (9) 1.2. One gram - mole of methyl chloride vapor is contained in a vessel at 100C and 10 atm. 1.2.1. Use the ideal gas equation of state to estimate the system volume. 1.2.2. Suppose the actual volume of the vessel is 2.8 litres. What percentage error results from standard conditions. (3) [15 Marks] QUESTION 2 2. Air at 300C and 130kPa flows through a horizontal 7-cm ID pipe at a velocity of 42 m/s? 2.1. Calculate Ek(W), assuming ideal gas behaviour. 2.2. If the air is heated to 400C, at constant pressure, what is Ek=Ek(400C)Ek (300C)
