What how many degrees variation is there between the highest temperatures and lowest temperatures on the moon? about 550ºC about
kirill [66]

Answer:

about 310ºC

Explanation:

The Moon is the natural satellite of the Earth.

The Moon orbits around the Earth in approximately 27 days, and its average distance from the Earth is about 380,000 km.

Moreover, the mass of the Moon is 7.35\cdot 10^{22}kg.

The Moon has no water on its surface and no atmosphere: due to the lack of atmosphere, heat coming from Solar radiation is not retained near the surface. Moreover, the Moon orbits around the Earth keeping one face always towards it, so every location on the Moon has 13 consecutive days of daylight followed by 13 days of darkness.

As a result, there is a large thermic excursion between the maximum and minimum temperature on the Moon. In particular, we have:

- Minimum temperature: -173 degrees Celsius

- Maximum temperature: +127 degrees Celsius

So this difference is about

\Delta T = 127-(-173)=300^{\circ}C

So, about 310ºC.

Which of these could be separated by physical means such as distillation or filtration?
Mama L [17]
Something that can be separated by physical means implies that there is a noticeable difference between the two components when mixed together. For example, salt water has a noticeable difference in that the boiling points of water and salt are so different that the water can be separated by evaporation. The only thing that can be separated by physical means is a mixture.
