5. A cylinder with a movable piston contains 0.41 mole of helium gas. The piston is open to the atmosphere on the top and has a mass of 30 kg and a radius of 0.1 m. The gas and cylinder are in equilibrium with the atmosphere, which has a temperature of 290 K and pressure of 1.00 x 10s Pa. The initial volume of the helium inside the cylinder is 0.0090 m when a 60-kg mass is placed on top...

Suppose a small sample of pure X is held at -9. °C and 1.1 atm. What will be the state of the sample? ✓ (chole one) solid liquid gas Suppose the temperature is held constant at -9. °C but the pressure is decreased by 0.7 atm. What will happen to the sample?...
A gas cylinder initially contained 49.5L of Ar gas at a pressure of 85.0 atm and a temperature of 24oC. Then 1250g of Ar gas were removed from the cylinder. What is the new pressure of the gas, which remains in the cylinder? The cylinder volume and temperature do not change. *** Show your work THE ANSWER IS 69.6atm but please show how to get there thanks!!
A high-pressure gas cylinder contains 70.0 L of toxic gas at a pressure of 1.50x10^7 N/m2 and a temperature of 24.0°C. Its valve leaks after the cylinder is dropped. The cylinder is cooled to dry ice temperatures (−78.5°C), to reduce the leak rate and pressure so that it can be safely repaired. (a) What is the final pressure in the tank, assuming a negligible amount of gas leaks while being cooled and that there is no phase change? N/m2 (b)...
He gas is confined to a piston and cylinder with a mechanical stop that prevents the cylinder from expanding. The temperature of the gas is 298 K, the volume of gas in the cylinder is 1.20 L and its pressure is 2.15 bar. The ideal gas EOS is very accurate for He under these conditions. Starting from the final state of the He gas in part (b), the gas (and apparatus) was cooled from 298 K to 263 K. The...
A certain gas is present in a 15.0 L cylinder at 2.0 atm pressure. If the pressure is increased to 4.0 atm , the volume of the gas decreases to 7.5 L . Find the two constants ki, the initial value of k, and kf, the final value of k, to verify whether the gas obeys Boyle’s law.

3. Two kilograms of oxygen fills the cylinder of a piston-cylinder assembly. The initial volume and pressure are 2 m'and 1 bar, respectively. Heat transfer to the oxygen occurs at constant pressure until the volume is doubled. Assuming the ideal gas behavior determine the heat transfer for the process, in kJ. Kinetic and potential energy effects can be ignored. Given Cy = 0.742 kJ/kg-K. Oz V = 2V ! ! Patm = I am m = 2 kg Vi =...
105Pa, initial temperature T-300K, and an initial 1. An ideal gas with initial pressure 2 volume V - 1m3 expands isothermally to a final volume of 2m3. Then, the gas returns to its initial state, first by constant pressure (isobaric) contraction, and then by a change at constant volume (isochoric) a) Draw a PV diagram of this process. What's the total change in thermal energy of the entire process? b) What's the work done by the environment on the gas?...
