Q. What happens when air is cooled to its dew point?
Water vapor in the air reaches its dew point as it cools in the air around the can, forming liquid drops of water. Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor.

Q. What happens to dew point as temperature increases?
The dew point is always below the air temperature. This is because you can’t have relative humidly higher that 100%. So, increasing temperature has no effect on dew point. At this point water will start condensing out of air, thus lowering it’s humidly and thus it’s dew point.
Q. Why does air cool to the dew point as it rises up the side of a mountain?
The idea is that if air is forced to rise over a mountain the air will cool, the SMR will drop, the RH will increase and dew point (DP) may be reached. If DP is reached and the air is forced to rise and subsequently cool further, precipitation will occur.
Q. Is it healthier to live in higher altitudes?
Living at higher altitudes seems to be associated with lower mortality from cardiovascular diseases, stroke and certain types of cancer. In contrast mortality from COPD and probably also from lower respiratory tract infections seems to be increased.
Q. Does High Altitude affect blood thinners?
Barbiturates sedatives and alcohol should be used with caution. Blood thinners also can act differently at altitude and anyone taking these medications should consult with a physician and have their INR/prothrombin times monitored closely when they first arrive at altitude.
Q. Can you fly while on blood thinners?
Car or plane trips can raise DVT risk, because you’re inactive for long periods of time. Taking a blood thinner makes it less likely that you’ll get a clot, but “it’s still smart to get up and move around every hour or two,” Dr.
Q. What altitude is safe for heart patients?
Despite a possible imbalance between oxygen demand and oxygen delivery, studies on selected patients have shown that exposure and exercise at altitudes of 3000 to 3500 m is generally safe for patients with stable CHD and sufficient work capacity.
Q. How long does it take your body to adjust to altitude?
The major cause of altitude illnesses is going too high too fast. Given time, your body can adapt to the decrease in oxygen molecules at a specific altitude. This process is known as acclimatization and generally takes 1-3 days at that altitude.
