A closed container with constant volume insulated against heat is divided into two compartments by a steel curtain. Achamber contains 2 kg of water at 800 kPa pressure and 80 oC temperature. The other compartment isis empty (vacuum). Then the steel curtain is removed and the water fills the whole container. EndIn the equilibrium state, since the pressure of the water is 10 kPa, the final temperature of the water andCalculate the volume of the tank.
Acetylene had many uses at the time of the First World War, because it burned with a hot and luminous flame mainly. The oxyacetylene apple and the period of the oxyacetylene car company and bicycles made this good represent well. In an attempt to find a route to acetylene other than through calcium carbide, a Prest-O-Lite sponsored research by George O. Curme of the Mellon Institute in Pittsburgh. Ethylene research was directed towards converting gases for refining petroleum methods, led to more polyethylene material for acetylene production. Viewed from today's perspective, the Curme route to petroleum-based ethylene ranks as an important discovery. However, this was not the case at the time, because ethylene had almost no use before 1920. Curme's second major contribution was the research he carried out to see what useful products he could make with ethylene. The first was ethylene glycol, which became Prestone antifreeze. Others follow and now ethylene is evidently the most…
To evaluate the use of renewable resources, an experiment was carried out with rice hulls. After pyrolysis, the product gas analyzed 6.4% CO2, 0.1% O2, 39% CO, 51.8% H2, 0.6% CH4, and 2.1% N2. It entered a combustion chamber at 90 °F and a pressure of 35.0 in. Hg and was burned with 40% excess air (dry) at 70 °F and an atmospheric pressure of 29.4 in. Hg; 10% of the CO remains. a. How many cubic feet of air were supplied per cubic foot of entering gas? b. How many cubic feet of product gas were produced per cubic foot of entering gas if the exit gas was at 29.4 in. Hg and 400 °F?

An ideal gas confined to a container with a massless piston at the top. A massless wire is attacted to the piston. When an external pressure of 2.00 atm is applied to the wire, the gas compresses from 4.90 to 2.45L. When the external pressure is increased to 2.50 atm, the gas futher compresses from 2.45 to 1.96L In a seperate experiment with the same initial conditions of 2.50 atm was applied to the ideal gas, decreasing its volume from 4.90 to 1.96L in one step. If the final temperture was the same for both processes, what is the difference between q for the two step pocess and q for the one process in joules?

The label has come off a cylinder of gas in your laboratory. You know only that one species of gas is contained in the cylinder, but you do not know whether it is hydrogen, oxygen, or nitrogen. To find out, you evacuate a 5-liter flask, seal it and weigh it, then let gas from the cylinder flow into it until the gauge pressure equals 1.00 atm. The flask is reweighed, and the mass of the added gas is found to be 13.0 g. Room temperature is 27°C, and barometric pressure is 1.00 atm. What is the gas?
