give the reasons for mercury having very high temperatures.

how hot is Mercury? Well, that depends on where you are on the planet’s surface. There is a tenuous, at best, atmosphere on Mercury. That means that the planet does not retain the heat it receives from the Sun as it rotates. The side facing the Sun is amazingly hot, around 700 Kelvin (430 °C), yet that same place on the planet can plunge to 110 Kelvin (-163 °C) when it is on the dark side. Due to the planets axial tilt, some parts of the poles never receive sunlight and can stay at 90 Kelvin (-183 °C). Given those figures, the average(median) temperature of the Mercurian surface is 452 Kelvin (179 °C).
Mercury is the smallest planet in the Solar System and orbits the Sun every 87.969 Earth days. At this time it does not have a moon, but some scientists speculate that it may have had a moon in the ancient past. It is their contention that the orbit of Mercury’s moon decayed and it impacted the surface of the planet. The planets has an apparent magnitude that ranges from ?2.3 to 5.7 and would easily be seen with the unaided eye if it were not so close to the Sun.

Very high because it is close to the sun. Cold because it has little atmosphere and the part that faces away from the sun (night) has no "blanket" to keep it warm.

Bcoz it is very near to the sun, the sun rays are too harm and makes the mercury temp hot and no water.
