A rigid tank is divided into two compartments by a membrane. One compartment contains 22 kg of CO2 at 25°C and 100 kPa, and the other compartment con

Two evacuated bulbs are connected by a tube of negligible volume. The volume of one of the bulbs is twice that of the other. The larger volume bulb is placed in a 200K Isother constant-temperature bath and the other in a 300K bath, and then 1.00mol of an ideal me gas is injected into the system. Find the final number of moles of gas in each bulb.

A closed system consisting of 2 lb of a gas undergoes a process during which the relation between pressure and volume is pV" = constant. The process begins with p₁ = 25 lbf/in², V₁ = 13 ft³ and ends with p2 = 100 lbf/in². The value of n = 1.3. Determine the final volume, V₂, in ft3, and determine the specific volume at states 1 and 2, in ft³/lb.

A sample of n = 2.00 moles of monoatomic ideal gas expands adiabatically, the work done on the gas is W = -5.00 x 103 J.  The initial temperature and pressure of the gas are   Ti = 600 K and Pi = 4.05 x 105 Pa.  Calculate: a) the final temperature of the gas; b) the final pressure of the gas.  R = 8.314 J/mol K

5kg on it which can slide up and A cylinder with an ideal gas has a piston of mass m = down and does not permit the gas to escape. The inner radius of the cylinder is r = 6cm, The top of the piston is open to atmospheric pressure. The entire system is initially in thermal equilibrium with the environment, which is at 20°C and the height of the piston h = 10cm. If the temperature of the gas inside then is raised to 100°C, what is the final height of the piston?

A) A rigid tank contains 1.60 moles of helium, which can be treated as an ideal gas, at a pressure of 28.0 atm. While the tank and gas maintain a constant volume and temperature, a number of moles are removed from the tank, reducing the pressure to 5.00 atm. How many moles are removed? B) What If? In a separate experiment beginning from the same initial conditions, including a temperature Ti of 25.0°C, half the number of moles found in part (a) are withdrawn while the temperature is allowed to vary and the pressure undergoes the same change from 28.0 atm to 5.00 atm. What is the final temperature (in °C) of the gas?

On a hot summer day, the density of air at atmospheric pressure at 34.5°C is 1.1866 kg/m³.

What is the mass of 1.00 m³ of air? (Assume air is an ideal gas.) kg (c) Does the value calculated in part (b) agree with the stated density of air at this temperature? (Consider that it does if the values are within 10% of each other.) O Yes O No

(a) A rigid tank contains 1.50 moles of carbon dioxide, which can be treated as an ideal gas, at a pressure of 22.7 atm. While the tank and gas maintain a constant volume and temperature, a number of moles are removed from the tank, reducing the pressure to 5.10 atm. How many moles are removed? mol (b) What If? In a separate experiment beginning from the same initial conditions, including a temperature T, of 25.0°C, half the number of moles found in part (a) are withdrawn while the temperature is allowed to vary and the pressure undergoes the same change from 22.7 atm to 5.10 atm. What is the final temperature (in °C) of the gas? °C

An ideal diatomic gas undergoes an adiabatic compression during which time its volume changes from VA = 1300 cm3 to VB = 390 cm3. If its initial temperature is TA = 74.0°C, what is the final temperature TB of the gas?

(a) What is the gauge pressure in a 25.0oC car tire containing 3.60 mol of gas in a 30.0 L volume? (b) What will its gauge pressure be if you add 1.00 L of gas originally at atmospheric pressure and 25.0oC? Assume the temperature returns to 25.0oC and the volume remains constant.
