Venus revolves or orbits around the Sun once every 0.615 Earth years, or once every 224.7 Earth days. Venus travels at an average speed of 78,341 miles per hour or 126,077 kilometers per hour in its orbit around the Sun.
5 Sol-Air Temperature Sol-air temperature (Tsol) is the fictitious temperature of the outdoor air which, in the absence of radiative exchanges on the outer surface of the roof or wall, would give the same rate of heat transfer (Q) through the wall or roof as the actual combined heat transfer mechanism between the sun, the surface of the roof or wall, the outdoor air and the surroundings.
At the top of the troposphere is a thin layer called the tropopause. Temperature in the tropopause does not change with height. This means that the cooler, denser air of the troposphere is trapped beneath the warmer, less dense air of the stratosphere. layer of ozone molecules absorbs solar radiation, which heats the stratosphere. Unlike in the troposphere, air in the stratosphere is stable because warmer, less dense air sits over cooler, denser air. As a result, there is little mixing of air within the layer.
