A100 g aluminum calorimeter contains 250 g of water. the two substances are in thermal equilibrium at 10°c. two metallic blocks are placed in the water. one is a 50 g piece of copper at 66°c. the other sample has a mass of 71 g and is originally at a temperature of 100°c. the entire system stabilizes at a final temperature of 20°c. determine the specific heat of the unknown second sample.

increases it

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.
