Which jovian planets do not have internal heat source?
Uranus and Neptune are the two jovian planets that do not have a significant internal heat source. They receive most of their heat from the sun and do not generate as much internal heat as Jupiter and Saturn.
Which is the coldest planets?
Neptune or Uranus is the coldest Planet. Some reference sources say it's Neptune others say it's Uranus. There's very little difference between them. Neptune is the furthest from the Sun, but it has an internal heat source.
Which planet is the coldest why?
Neptune is the furthest away from the Sun, but it has an internal heat source. So, Uranus may be the coldest. Their surface temperatures are certainly very similar.
How can Neptune have 1000 mph winds with out a heat source?
Because Neptune does have a heat source. It generates about 2.6 times more energy that it receives from the Sun. This may be due to radiogenic heating [See related link] but we're not too sure.
Is there heat on Neptune?
Neptune does not have a significant internal heat source like other planets such as Earth or Jupiter. Its heat mainly comes from the Sun, with temperatures on the surface averaging around -200 degrees Celsius. The planet's deep atmosphere absorbs sunlight and generates strong winds and storms, but it is not considered a hot planet.
What are physical charateristics of Neptune?
Since the Neptune Orbit so far from the sun, it receives very small amount of heat and indeed the uppermost region of the atmosphere is -218 °C (55 K). There is no solid surface due to the fact that Neptune is a gas giant. Atmospheric temperatures gradually rise as you go deeper inside Neptune due to an internal source of heat. It is thought that this may be leftover heat generated by in falling matter during the planet's birth, right now slowly radiating away into space. Neptune's atmosphere has the highest wind speeds in the solar system, up to 2000 km/h, thought to be powered by this flow of internal heat. The internal structure resembles that of Uranus.
What are the internal heat source?
Internal heat source include celestial objects, such as moons, dwarf planets, brown dwarfs, stars and planets.
Is Neptune volcanically active?
Neptune is not believed to be volcanically active due to its cold temperatures and lack of a significant internal heat source. However, its moon Triton shows evidence of past cryovolcanic activity, where icy materials were erupted from beneath its surface.
A heat engine is unable to convert its entire heat source into work?
False (APEX)
Is this truth or false the heat source for the convection currnets in the mantle is the sun?
False.
Is Neptune the coldest planet in the solar system?
Yes. But it has a hotspot. Neptune is -329.8 F. That's pretty cold if you ask me. In fact, Uranus is usually said to be the coldest planet, but it is very similar to Neptune in its average surface temperature. Neptune us further from the Sun than Uranus, but it seems to have a internal heat source which warms the surface a bit.
A heat engine is able to convert its entire heat source into work?
False
