1. in 1 L of water at a temperature of 30°C, insert an iron ball weighing 120 g heated to 95°C. determine the temperature of the mixture. 2. in water of temperature 25°C we pour water of the same mass, but temperature 70°C. what is temperature of the mixture? ​

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
