Q. 6

  1. How much greater is the average temperature on Earth than that on Mars?

    15-(-63) = 78 \deg C

  2. Volume of mars in standard form

    \Rightarrow 162000 \times 10^6 \Rightarrow 1.62 \times 10^{11}

  3. \Delta Earth \, and \, Mars \Rightarrow (5.98 \times 10^21) - (6.58 \times 10^20) \Rightarrow (59.8 \times 10^20) - (6.58 \times 10^20) \Rightarrow 53.22 \times 10^{20} \Rightarrow 5.322 \times 10^{20}
