The thermosphere is the layer of the atmosphere with the hottest temperature. however, if pete the astronaut traveled to the thermosphere he would feel very cold. explain why this is.

The Earth's thermosphere - consists of both the ionosphere and the exosphere, which feels cold because of the low density of air at that level. Measurements of air temperature reveal how energetic the measured particles are, but with fewer particles, the thermosphere is unable to effectively transfer heat. Heat may be transferred by direct contact between 2 surfaces; convection from one surface to another or by radiation. Energetic particles in the thermosphere to radiate heat, but the very low density of particles limit the amount of energy available to the zone as a whole, so the radiation remains relatively weak.

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.

                             

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.
