- 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?One hundred moles of hydrogen gas at 298K are reversibly and isothermally compressed from 30 to 10 L. The van der Waals constants for hydrogen are a = 0.2461 L².atm/mole² and b = 0.02668/mol. In the pressure range of 0 to 1500 atm, the virial equation for hydrogen is PV = RT(1+6.4×10-4P), where P is in atmospheres. (a) Calculate the final pressure and fugacity if (i) Hydrogen behaves as an ideal gas (ii) Hydrogen behaves as a van der Waals gas (iii) Hydrogen behaves according to the virial equation. (b) Calculate the magnitude of the work that must be done on the system to achieve the required change in volume if hydrogen behaves according to the virial equationYou have four samples of ideal gas, each of which contains the same number of moles of gas and has the same initial temperature, volume, and pressure. You compress each sample to one-half of its initial volume. Rank the four samples in order from highest to lowest value of the final pressure. (i) A monatomic gas compressed isothermally; (ii) a monatomic gas compressed adiabatically; (iii) a diatomic gas compressed isothermally; (iv) a diatomic gas compressed adiabatically.
- A volumetric flask made of Pyrex is calibrated at 20.0°C. It is filled to the 220-mL mark with 42.0°C Mercury. After the flask is filled, the Mercury cools and the flask warms so that the combination of Mercury and flask reaches a uniform temperature of 32.0°C. The combination is then cooled back to 20.0°C. (The average volume expansion coefficient of Mercury is 1.82 10-4(°C)−1.) a. What is the volume of the Mercury when it cools to 20.0°C? b. At the temperature of 32.0°C, does the level of Mercury lie above or below the 220-mL mark on the flask? Explain.A compressed air tank contains 4.7 kg of air at a temperature of 81 °C. A gage on the tank reads 300 kPa. Determine the volume of the tank. volume = i m³ 3Imagine that you have a 6.50 L gas tank and a 2.50 L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.

Assume ideal behaviour for all gases. Express your answer with the appropriate units.
