A system of ideal gas has an initial pressure of 114 kPa and
occupies a volume of 6.00 liters. Doubling the system’s absolute
temperature by means of a constant-pressure process would require
an amount of work W. Instead, you decide to double the absolute
temperature by carrying out two processes in sequence, a
constant-pressure process followed by a constant-volume process. In
this case, the total work done in the two-process sequence is
W/2.
Calculate the final pressure of the system.
_______ kPa

A system of diatomic ideal gas is in an initial state such that the pressure is 69.0 kPa and the volume occupied by the gas is 6.00 L. The system then experiences a compression at constant temperature that raises the pressure to 165 kPa. (a) Calculate the final volume occupied by the gas. __L (b) Calculate the work done by the gas in this process. (Include the sign of the value in your answer.) __J Please show all work!
An ideal gas with γ=1.4 occupies 5.0 L at 300 K and 100 kPa pressure and is heated at constant volume until its pressure has doubled. It's then compressed adiabatically until its volume is one-fourth its original value, then cooled at constant volume to 300 K , and finally allowed to expand isothermally to its original state. Find the net work done on the gas in Joules.
An ideal gas is at a pressure 1,19 × 105 N/m2 and occupies a volume 2,42 m3. If the gas is compressed to a volume 1 m3 while the temperature remains constant, what will be the new pressure (MPa) in the gas? Answer in two decimal places.
A sample of ideal gas at room temperature occupies a volume of 11.0 L at a pressure of 732 torr . If the pressure changes to 3660 torr , with no change in the temperature or moles of gas, what is the new volume, V2? Express the volume numerically in liters. Part B) If the volume of the original sample in Part A (P1 = 732 torr , V1 = 11.0 L ) changes to 74.0 L , without a...
With the pressure held constant at 230 kPa, 44 mol of a monatomic ideal gas expands from an initial volume of 0.80 m3 to a final volume of 1.9 m3. Review PartA With the pressure held constant at 230 kPa, 44 mol of a monatomic ideal gas expands from an initial volume of 0.80 m3 to a final volume of 1.9 m3 How much work was done by the gas during the expansion? Express your answer using two significant figures....
A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 2.50 L and the pressure is initially 125 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 80.0 J of work is then done on the piston, compressing the gas (in other words, the gas does -80 J of work). The work is done very slowly so that the gas maintains a...
The ideal gas law relates the temperature, pressure and volume of an ideal gas. Suppose the gas inside a particular balloon has an absolute pressure of 3.15×105 Pa and occupies a volume of 5.33×10-3 m3 at a temperature of 16.7°C. How many moles of gas are inside the balloon? (do not enter units) How many molecules of gas are inside the balloon? (do not enter units)
If a certain amount of ideal gas occupies a volume 6.4 m3 with a pressure of 6.1 atm and temperature 1.7 oC on earth, what would be its volume on another planet, where the temperature is 3.3oC and the pressure is 7.7 atm ? The answer is in unit of m3
A polytropic process for an ideal gas in one in which pressure and volume are related by = const., where n is a constant. It is a generalization of the special processes considered earlier. Thus n = 0 defines an isobaric process, n = cp/cv an adiabatic process, n = 1 an isothermal process, and n = 8 an isochoric process. Suppose 1 kg of dry air at 280 K and 100 kPa undergoes a polytropic expansion in which the...
