Oxy-acetylene torches can be used to cut or weld metal. Oxygen and acetylene are fed from separate compressed gas cylinders through pressure regulators to the torch where they are mixed and combusted. To estimate the amount of metal that can be cut or welded per unit volume of gas, the composition of the gases produced by combustion and heat produced by the combustion reaction must be determined. For this problem: a. Define a closed system that can be used to calculate the heat produced o. Define an open system that can be used to calculate the heat produced c. List at least two intensive variables that are important in calculation d. List at least two extensive variables that are important in the calculation

= O STATES OF MATTER Using the ideal equation of state A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 59.0 cm wide and 70.8 cm high. The maximum safe pressure inside the vessel has been measured to be 2.40 MPa. V For a certain reaction the vessel may contain up to 2.16 kg of carbon monoxide gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction.
