What is the relationship between temperature and altitude in the stratosphere? (2 points).
stealth61 [152]
As altitude increases, temperature increases. The stratosphere is the part of the atmosphere that starts in the tropopause and ends in the estratopause. In the troposphere, the air is close to the Earth surface. The air surface can absorb more sunlight energy than the air, so the Earth surface heats the air. As you go higher, the distance to the Earth surface is higher, so the temperature is lower. The troposphere ends in the tropopause, where this trend changes. In the estratopause, there is a lot of ozone, which absorbs the dangerous UV radiation and converts into heat. That heat warms the air. So the air which is close to the estratopause is warm because of the heat released by the ozone reactions. The tropopause is far from the Earth surface and far from the ozone layer, that’s why it is cold. So the tropopause is cold and the estratopause is warm, which means: the air becomes warmer <span>as you rise above the tropopause until you get to the estratopause.</span>

If you want to make a strong battery, should you pair two metals with high electron affinities, low electron affinities, or a mi
zalisa [80]

A mix

Explanation:

A battery is an electrochemical cell that converts chemical energy into electrical energy. The chemical reactions in a battery ensures that current is produced.

  • A battery is made up of two electrodes which are the cathode and anode.
  • The cathode is the positive electrode and the anode is the negative one.
  • These electrodes are made up of metals.
  • Electrons moves from the anode to the cathode and current flows from cathode to anode.
  • At the anode oxidation occurs because electrons are produced here.
  • It needs to have low electron affinity.
  • At the cathode where reduction occurs, the electron affinity must be high.
  • This is the driving force for the production of electricity in electrochemical cells.
