Chapter 10: Problem 94

The planet Jupiter has a surface temperature of \(140 \mathrm{~K}\) and a mass 318 times that of Earth. Mercury (the planet) has a surface temperature between \(600 \mathrm{~K}\) and \(700 \mathrm{~K}\) and a mass 0.05 times that of Earth. On which planet is the atmosphere more likely to obey the ideal-gas law? Explain.

Short Answer

Expert verified
Based on the analysis, the atmosphere of Mercury is more likely to obey the ideal gas law compared to Jupiter. Mercury's higher temperature (between 600 K and 700 K) and lower mass (0.05 times Earth's mass) relative to Jupiter (whose temperature is 140 K and has a mass 318 times Earth's mass) make it more likely to meet the conditions necessary for the ideal gas law to be a valid approximation.

Step by step solution

01

1. Jupiter's characteristics

Jupiter has a surface temperature of 140 K and a mass 318 times that of Earth.
02

2. Mercury's characteristics

Mercury has a surface temperature between 600 K and 700 K, and a mass 0.05 times that of Earth.
03

3. Comparing temperatures

Jupiter has a lower temperature (140 K) when compared to Mercury's temperature range (600 K - 700 K).
04

4. Comparing masses

Jupiter has a much larger mass (318 times Earth's mass) compared to Mercury's mass (0.05 times Earth's mass).
05

5. Analyzing ideal gas law conditions

As stated earlier, the ideal gas law tends to work well when the gas particles have high temperatures and low densities. Since Mercury's temperature is higher than Jupiter's, it indicates that the gas particles on Mercury will have more energetic motion, reducing the significance of any intermolecular attractive forces. Additionally, Jupiter's larger mass implies that it likely has a more dense atmosphere than Mercury, which would lead to more deviations from the ideal gas law due to increased particle interactions.

6. Conclusion:

Based on the analysis, the atmosphere of Mercury is more likely to obey the ideal gas law compared to Jupiter. Mercury's higher temperature and lower mass relative to Jupiter make it more likely to meet the conditions necessary for the ideal gas law to be a valid approximation.

A sample of \(3.00 \mathrm{~g}\) of \(\mathrm{SO}_{2}(g)\) originally in a \(5.00-\mathrm{L}\) vessel at \(21^{\circ} \mathrm{C}\) is transferred to a \(10.0-\mathrm{L}\) vessel at \(26^{\circ} \mathrm{C}\). A sample of \(2.35 \mathrm{~g} \mathrm{~N}_{2}(g)\) originally in a \(2.50-\mathrm{L}\) vessel at \(20{ }^{\circ} \mathrm{C}\) is transferred to this same 10.0 - \(\mathrm{L}\) vessel. (a) What is the partial pressure of \(\mathrm{SO}_{2}(g)\) in the larger container? (b) What is the partial pressure of \(\mathrm{N}_{2}(g)\) in this vessel? (c) What is the total pressure in the vessel?

Carbon dioxide, which is recognized as the major contributor to global warming as a "greenhouse gas," is formed when fossil fuels are combusted, as in electrical power plants fueled by coal, oil, or natural gas. One potential way to reduce the amount of \(\mathrm{CO}_{2}\) added to the atmosphere is to store it as a compressed gas in underground formations. Consider a 1000 -megawatt coalfired power plant that produces about \(6 \times 10^{6}\) tons of \(\mathrm{CO}_{2}\) per year. (a) Assuming ideal-gas behavior, \(1.00 \mathrm{~atm}\), and \(27^{\circ} \mathrm{C},\) calculate the volume of \(\mathrm{CO}_{2}\) produced by this power plant. (b) If the \(\mathrm{CO}_{2}\) is stored underground as a liquid at \(10^{\circ} \mathrm{C}\) and \(120 \mathrm{~atm}\) and a density of \(1.2 \mathrm{~g} / \mathrm{cm}^{3},\) what volume does it possess? (c) If it is stored underground as a gas at \(36^{\circ} \mathrm{C}\) and \(90 \mathrm{~atm},\) what volume does it occupy?

A set of bookshelves rests on a hard floor surface on four legs, each having a cross-sectional dimension of \(3.0 \times 4.1 \mathrm{~cm}\) in contact with the floor. The total mass of the shelves plus the books stacked on them is \(262 \mathrm{~kg} .\) Calculate the pressure in pascals exerted by the shelf footings on the surface.

A fixed quantity of gas at \(21^{\circ} \mathrm{C}\) exhibits a pressure of 752 torr and occupies a volume of 5.12 L. (a) Calculate the volume the gas will occupy if the pressure is increased to 1.88 atm while the temperature is held constant. (b) Calculate the volume the gas will occupy if the temperature is increased to \(175^{\circ} \mathrm{C}\) while the pressure is held constant.

The molar mass of a volatile substance was determined by the Dumas-bulb method described in Exercise \(10.55 .\) The unknown vapor had a mass of \(0.846 \mathrm{~g} ;\) the volume of the bulb was \(354 \mathrm{~cm}^{3}\), pressure 752 torr, and temperature \(100{ }^{\circ} \mathrm{C}\). Calculate the molar mass of the unknown vapor.
