Mercury. At the equator, the surface temperature on Mercury can range from 100K (-173'C) to 700K (430'C). This is due to a very long apparent day length, from a combination of the time taken to orbit and the planets axial rotation. The lack of atmosphere also means that heat is not retained by the planet, despite being the closest to the sun.
Mercury with a surface temperature of 700K in the daytime and 100K in the night
Temperate Temperate
The Answer is B. Temperate
In order to decrease the friction an object experiences, you can either change the surface of the object or the surface it's in contact with. This can be achieved by using lubricants, smooth materials, or reducing the weight of the object pressing against the surface.
temperate. 100%
temperature increases with depth
In general, the temperature decreases towards the surface.
The coefficient of superficial expansion refers to the ratio of change in area to an increase in its temperature. It measures the expansion of a Laminar surface.

In order to decrease the friction an object experiences, you can either change the surface it sits on to a smoother material or decrease its weight to reduce the force pressing it against the surface, both of which would lower the frictional force acting on the object.
