The Summer Factor: Temperature. Temperature also affects density altitude. When you heat the air, the air molecules have more energy. And, when they have more energy, they spread farther apart. (You probably learned this in high school chemistry class...). When the air is warmer than standard, it's less dense and performance decreases.
There are two factors that influence air resistance with temperature. Air density decreases with temperature so that the force needed to push the air out of the way is decreased, thereby decreasing resistance.Conversely, air viscosity increases with temperature (unlike oil for example where viscosity decreases with temperature) so that the drag increases.he air resistance of an object is proportional to the object's velocity, and the surface area of the object that is in contact with the air.
