Gas giants generally have lower average temperatures than terrestrial planets due to their greater distance from the Sun, which results in less solar energy absorbed. Additionally, their thick atmospheres, composed mainly of hydrogen and helium, do not retain heat as effectively as the rocky surfaces of terrestrial planets. This combination of distance and atmospheric composition contributes to their cooler overall temperatures.
No, Earth is not hotter than the gas giants. The gas giants, such as Jupiter and Saturn, have extremely high temperatures in their deep atmospheres due to the immense pressure and heat generated by their massive size and gravitational compression. In contrast, Earth's average surface temperature is much cooler, typically around 15 degrees Celsius (59 degrees Fahrenheit). However, Earth can experience higher surface temperatures than some of the outer layers of gas giants, but overall, the internal temperatures of gas giants far exceed those on Earth.
The gas giants are composed of hydrogen and helium, which can remain in a gaseous state at extremely low temperatures, even lower than thous found in the atmospheres of the gas giants. In reality, though, most of the volume of the gas giants is not gas. Deep within the atmospheres of these planets the enormous pressure renders the hydrogen and helium into a supercritical state, which is characteristics between those of a liquid and a gas. Even deeper the hydrogen enters an exotic metal-like state. The interiors of the gas giants are very hot.
The temperatures on gas giants like Jupiter and Saturn are low because their atmospheres are primarily composed of hydrogen and helium, which do not trap heat well. Additionally, these planets are located far from the Sun where solar radiation is weaker, contributing to their colder temperatures.
No, temperatures generally do not decrease from the outer to inner layers of gas giants. Instead, as you move deeper into the atmosphere of gas giants like Jupiter or Saturn, temperatures typically increase due to the immense pressure and gravitational compression. This rising temperature is a result of the increasing density and pressure of the gases, leading to complex thermal dynamics within these planets.
they are farther from the sun
The gas giant planets (Jupiter, Saturn, Uranus, and Neptune) are much farther from the Sun than the inner planets, and so receive less solar heating. They are very hot in their interiors, however, due to compression from the large overlying atmosphere.It is difficult to accurately theorize what their mass, size, and composition would be if they were in closer orbits, but they would have higher average temperatures. The second reason for the low average temperature of gas giants is their large diameter, with a greater volume of atmosphere farther from the layers that have higher compression and heat retention. Even for Earth, the majority of the atmosphere (in the higher altitudes) is extremely cold by surface standards.

Uranus is classified as an ice giant, not a gas giant or terrestrial planet. It is composed mostly of elements such as water, ammonia, and methane, which freeze at lower temperatures compared to the gases found in gas giants like Jupiter and Saturn.
The average terrestrial planet has only about 10.3% of the diameter and 0.4% of the mass of the average gas giant.
Exhaust Gas Recirculation. A small amount of exhaust gas is fed back into the cylinder to lower combustion temperatures and lower tail pipe emissions.
Not all gas giant planets have low temperatures (most exoplanets are hot "jupiters"). In our solar system the relatively low temperature are a result of the distance they are from the Sun.
Of the four gas giants; Jupiter, Saturn, Uranus and Neptune, Neptune is the smallest. Uranus is the least massive though, bigger than Neptune but lower in density and mass.
