A4.0-kg aluminum block is originally at 10°
c. if 160 kj of heat is added to the block, what is its final temperature? the specific heat capacity of aluminum is 910 j/kg · k

Heat gained in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:

Heat = mC(T2-T1)
160000= 4(910)(T2 - 10)
T2 = 53.96 degrees Celsius

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.
