In terms of comparing Venus with Earth using the ideal gas law its fairly simple, just ignore all the terms other than pressure and temperature and you'll see that Venus has a much higher surface temperature because it has a much higher surface pressure.

If you plug in whats known about Venus into the ideal gas law and solve for T you get a temperature of 735K, which is almost exactly Venus' real surface temperature.
You can ignore solar energy input entirely, the heat on Venus is entirely due to atmospheric pressure.

the volume is dependent on temperature, gasses expand when they're heated, you're already assuming the atmosphere is hot by choosing Venus's atmospheric volume.

the only things that would be kept constant in the equation by looking only at the total constituents of venus's atmosphere is the pressure, which has to be in equilibrium with the force of gravity, and the number of moles.

the planetary equilibrium temperature of Venus is is less than half the temperature due to atmospheric pressure and given the 4th power relationship between flux and temperature that means that the solar energy input is negligible compared to the energy created by the atmosphere crushing down on the surface. theres some level in the atmosphere near the top above which solar energy outweighs atmospheric pressure, below that Venus is hot for the same reason that to outer gas giants have high temperatures in their lower atmospheres.

>For a really strong greenhouse effect, we should look at Venus. Venus is similar to Earth in terms of size and mass, but its surface temperature is about 460 degrees Celsius. This is hot enough to melt lead! The Venusian atmosphere is mainly made up of carbon dioxide, a greenhouse gas. On Earth, carbon dioxide makes up only a tiny fraction of the atmosphere.

Did you mean Mars? Bad news there.

>As a complete contrast to Venus, there is Mars. The Red Planet displays hardly any greenhouse effect. Mars does have some atmospheric carbon dioxide, but almost no atmosphere!

mate according to your logic the temperature inside bicycle tires should be several hundred degrees because the pressure inside is higher. Not how it works.

Anonymous No. 16257120

>>16256791
Bicycle tyres are only 40-90 psi, not significantly higher than ambient surface pressure compared to 1350 psi on Venus. As the thin rubber is a poor insulator and attached to a metal frame, excess heat is quickly dissipated to the cooler ambient temperature outside the tire at rest. Your bike tire is immersed in a fluid system (our atmosphere) that can rapidly dissipate heat. So not a good comparison to the comparatively isolated system of an entire planet.
However, once you start riding your bike, the friction rapidly heats the air inside the tire.

>One of the most captivating aspects of Titan's atmosphere is the anti-greenhouse effect, a phenomenon that significantly shapes the moon's climate and surface conditions. Unlike Earth, where greenhouse gases absorb and re-radiate solar energy to warm the planet, Titan’s atmosphere operates differently due to its high concentration of methane, especially in the stratosphere. This methane functions as an "anti-greenhouse gas," by absorbing some incoming solar energy before it can reach the surface, leading to cooler surface temperatures than if methane were less abundant.

>When comparing the atmospheric temperature profiles of Earth[62] and Titan,[63] stark contrasts emerge. On Earth, the temperature typically increases as altitude decreases from 80 to 60 kilometers above the surface. In contrast, Titan’s temperature profile shows a decline over the same altitude range. This variation is largely due to the differing impacts of greenhouse and anti-greenhouse effects in Earth's and Titan's atmospheres, respectively.

By choosing a certain volume you therefore only have one possible temperature with everything else kept equal.

High pressure alone doesn't imply only a high temperature can satisfy the equation.
