    The mass of the atmosphere is 5.25 * 10 to the exponent 19 kg and that the specific heat capacity of dry air is 1050 joule/ (kg C) how many jouls does it take to raise the temperature of the atmosphere by 2 C ?

    right ok hmmm, so if the heat capicity of dry air is 1050 joule/(kg C), that means it takes 1050 joulels of energy to raise the temperature one degree C

    so it would take 5.25x10^19Kg * 1050 joule/KgC = 5.513 X 10^22 joules/C

    since you want to raise it 2 degrees, it's 1.10 * 10^20 joules (twice as much)

    2C * 5.513 X 10^22 joules/C = 1.10 X10^20 joules

    the point is multiple the kg * c * j/kgc = j (the number of joules)

    which is the mass * 2 degrees c * heat capacity
