Question

ideal gas: pV = nRT reversible adiabatic processes with ideal gas: TV??¹ = constant ? - 1 = 2/f 1. A 3-L sample of oxygen gas at 2 atm is adiabatically compressed to 1 L. What is the new pressure of the gas? 2. How much work is done by 3 moles of argon as its temperature changes from 25°C to 50°C adiabatically? (There is a hard way and an easy way to solve this.) 3. A cylinder of ideal gas is topped by a freely sliding massless piston of area 100 cm², with the internal and external pressure both 1 atm. A mass of 50 kg is suddenly placed on the piston and the gas is thereby compressed adiabatically to ¾ of its initial volume. Find ? for the gas. 50 kg
