The document is a multi-page tutorial by Dr. Waleed with his mobile number listed. On page 2, it shows a calculation of 22.3 x 6.895 = 153.75 kPa. Page 3 and 4 provide solutions to problems. On page 5, it discusses that a change of 1 K or 1°C in temperature corresponds to a change of 1.8 R or 1.8°F, and the boiling temperature decreases by 3 K or 5.4°F for every 1000 m increase in altitude.

Solution
The magnitudes of 1 K and 1°C are identical, so are the magnitudes of 1 R and
1°F. Also, a change of 1 K or 1°C in temperature corresponds to a change of 1.8 R
or 1.8°F.
Therefore, the decrease in the boiling temperature is
(a) 3 K for each 1000 m rise in altitude, and
(b), (c) 3×1.8 = 5.4°F = 5.4 R for each 1000 m rise in altitude.
