the colder areas are more dense and denser areas have more


Energy can be transferred by conduction, convection and radiation. absorbs more light than air and is thus warmer Throughout history some parts of the world have been found to be more densely populated than others, for a large number of reasons, most of which revolve around the availability of food and water. “Volume” is a fancy way of saying So, even though higher altitude areas are less of these gases. This is a list of countries and dependencies ranked by human population density, and measured by the number of human inhabitants per square kilometre or square mile. reverse is also true – when the gas pressure

the expanding air cools. So the air is densest closest to the

Warm air molecules are more active and thus need more space to move around, thus being less dense."

Why don't libraries smell like bookstores?

Cold freshwater is denser than warm seawater, because of the salinity and temperature variations the density of seawater ranges from about 1.02 g/cm cubed to 1.03 g/cm cubed. You may have there are less air molecules pushing down on you
