At the top of a hill a thermometer reads 0°C and a barometer reads 60 cm of Hg. At the bottom they read 20°C and 76 cm of Hg. Find the ratio of the air density at the top to that at the bottom (three decimals).
Answer:
0.85
Solution:
$ρ \propto (P) / (T)$ . Ratio $= ((60) / (273)) / ((76) / (293)) = 0.847$ .
