An ideal gas (the system) is contained in a flexible balloon at a pressure of 1 atm and is initially at a temperature of 1000.°C. The surrounding air is at the same pressure, but its temperature is 25°C. When the system has equilibrated with its surroundings, both systems and surroundings are at 25°C and 1 atm. In changing from the initial to the final state, which one of the following relationships regarding the system is correct?

8. An ideal gas is contained in a balloon. The gas within the balloon has a mass of 5 g and a molar mass of 30 kg/kmol. The balloon has an initial diameter of 20 cm and an initial temperature of 30° C. The gas is expanded through a polytropic process with ? = 1.1. This process increases the diameter of the balloon to 30 cm. Determine the pressure of the gas inside the balloon at the final state. Note:...

2 a) An ideal gas with a Cv of 1.5R independent of temperature is initially contained in a volume of 0.05 L at a pressure of 10 atm and an initial temperature of 1200°C. The volume is then increased to 0.50 L. What will be the final pressure and temperature of the gas if the total amount of gas is unchanged, and the gas undergoes reversible adiabatic expansion? How much work will be produced? Calculate the change in entropy of...

A Flexible Balloon A flexible balloon contains 0.315 mol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 7400 cm and a temperature of 29.0°C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp = 33.26 J/mol. K and y = 4/3. Part A What is the total heat...

A flexible balloon contains 0.350 mol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 6900 cm3 and a temperature of 30.0 ∘C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp=33.26J/mol⋅K and γ=4/3. What is the total heat Q supplied to the gas in the process? What is...

Question 4 of 21 A sample of an ideal gas at 1.00 atm and a volume of 1.76 L was placed in a weighted balloon and dropped into the ocean. As the sample descended, the water pressure compressed the balloon and reduced its volume. When the pressure had increased to 75.0 atm, what was the volume of the sample?

1) A cylinder is filled with 0.10 mol of an ideal gas at
standard temperature and pressure, and a 1.4-kg piston seals the
gas in the cylinder (see figure) with a frictionless seal. The
trapped column of gas is 2.1-m high. The piston and cylinder are
surrounded by air, also at standard temperature and pressure. The

An ideal monatomic gas is contained in a vessel of constant volume 0.470 m3. The initial temperature and pressure of the gas are 300 K and 5.00 atm, respectively. The goal of this problem is to find the temperature and pressure of the gas after 30.0 kJ of thermal energy is supplied to the gas. (a) Use the ideal gas law and initial conditions to calculate the number of moles of gas in the vessel. mol (b) Find the specific...
