What happens to the temperatures when we have direct sunlight vs indirect sunlight?
lawyer [7]

Explanation:

When we have direct sunlight, the temperature is higher compared to indirect sunlight.

Direct sunlight is usually overhead whereas indirect sunlight is at an angle to the surface.

  • Direct sunlight impacts the surface with more energy concentrated on a smaller surface area.
  • This warms the surface more.
  • Indirect sunlight is diffuse and spreads over a wider area.
  • This leads to a reduction in temperature.

What occurs when energy is removed from a liquid-vapor system in equilibrium
yulyashka [42]

<span>The answer is that the number of water molecules  increases and that of vapor decreases.  When energy is removed from the system it would do so mostly as heat. Therefore the energy in the system would decrease and the molecules would vibrate at lower energies. Therefore, several water vapor molecules would turn back to water.  </span>
