Unlike the other planets Mercury has a huge range in surface temperature due to lack of atmosphere. At the equator, the surface temperature on Mercury can range from 100K (-173'C) to 700K (430'C).**temperature at the 1.0 bar pressure level
Mercury -during the day it is very hot -at night it is very cold because of its slow rotation
The order of colors in a fire from hottest to coldest is blue, white, yellow, orange, and red. Blue flames are typically the hottest, followed by white, with yellow, orange, and red being cooler in temperature.
It is the coldest planet. If you include the Dwarf Planet Pluto, then Pluto is colder.

No, its one of the coldest planets as it is so far from the sun. Venus is the hottest planet (although Mercury is closer to the sun).
Mercury is an extreme planet. it is fastest of all the planets. also, it is one of the hottest and coldest planet too.

hottest temperature was 50.6 °C
Pluto is the coldest planet
all of our planets are heated by the sun. some more, some less! the hottest one would be mercury - being the closest and the coldest one theoretically would be Neptune. Hope this helps
Mercury is not the coldest planet because it has more solar radiation than all of the other planets. This is because it is closer to the Sun. However, Mercury is not the hottest planet in the Solar System. See related question.
Hottest - Venus. Mean Temperature is 462°C Coldest - Neptune. Mean Temperature is -214°C Though mercury comes very close to being the hottest and the coldest. As mercury has no atmosphere, the side which faces away from the sun reaches -210°C. And the side facing the sun reaches 427°C. At one time, the coldest planet would be Pluto, but Pluto is no longer a planet.
