The temperatures are alot hotter because of the carbon dioxide trapping in heat.
Venus
Venus has the highest surface temperatures in the solar system, with temperatures reaching up to 880 degrees Fahrenheit (471 degrees Celsius) due to its thick atmosphere of carbon dioxide and sulfuric acid clouds that trap heat.
The surface temperature of Venus is higher than the surface temperatures of the other inner planets because of its thick atmosphere.
Venus is often referred to as Earth's sister planet because they are similar in size and composition. Both planets have rocky surfaces and are located in the inner solar system. However, Venus has a very different atmosphere, with extreme temperatures and a thick layer of clouds made of sulfuric acid.
If you are talking about in our own solar system, and not Exo-Planets, then Venus and Earth are of almost identical size and mass. The only thing is Venus has a toxic atmosphere and acid rain, with temperatures that would boil water. While Earth... Well, you know what Earth is like.
It is about 480 degrees Celsius on Venus. Day and night temperatures are not much different.

The extreme temperatures on Venus and Mercury are due to their proximity to the Sun. Venus has a thick atmosphere that traps heat, creating a greenhouse effect. In contrast, Mercury has no atmosphere to retain heat, resulting in very hot temperatures on the side facing the Sun and very cold temperatures on the side facing away.
Temperatures on Venus don't get much below about 460 degrees Celsius.
No. Venus is very hot, with temperatures around 850 degrees Fahrenheit.
Yes. A typical fire will produce temperatures comparable to the surface of Venus.
No, Venus does not have a hydrosphere. The extreme temperatures and atmospheric conditions on Venus make it unable to support liquid water on its surface.
Approx 735 K.
Venus and Mars are often called Earth's twins because they are rocky planets like Earth, but they have different environments. Venus has a thick toxic atmosphere, while Mars has a thin atmosphere with extreme temperatures.
