Let's say that we have a layer of air with an initial temperature of 0°C and a depth of 310 m. This parcel then flows over an expanse with a temperature of -3°C. If the initial dewpoint of the air is -1°C, how far across the ground must the air travel before advection fog first forms. Please give your answer in kilometers!!! You can assume smooth ground with a roughness of 0.002 m. Please tell me the following: What equation(s)...

Note in passing: We will consider that a parcel that is saturated (contains cloud droplets) will warm at the moist adiabatic rate (here, 5°C) when it sinks, until the cloud droplets evaporate. Continued descent will then produce warming at the dry adiabatic rate. This process is called a reversible moist adiabatic process. Suppose we have a cloudy parcel at a temperature of 10°C at 1km height. The parcel sinks to cloud base at 800 m height and then continues to...

The density of air at standard temperature and pressure (STP) is 1.20 kg/m3. If the density of helium is 0.179 kg/m3 inside a perfectly spherical balloon of radius 5.00 m, how much mass, in kg, could this balloon carry?

We consider a hot-air balloon of mass 231 kg (basket and envelope). The spherical envelope of the balloon has a diameter of 15 m when fully inflated. To what temperature (in °C) must the enclosed air be heated for the balloon to carry five standard men? Assume the surrounding air is at 20°C and is treated as an ideal gas. Use 29 g/mol for the molar mass of air. (Assume the mass of each standard man is 70 kg.)
