Why does relative humidity drop if I open the window in winter? What about the temperature d...
We know how to calculate the saturated water vapour pressure for temperature $T$:
$$e_s(T)=e_{s0}e^{\frac{h_i}{R_w}(\frac{1}{T_{s0}}-\frac{1}{T})}=610\text{ Pa} \times e^{5423(\frac{1}{273\text{ K}}-\frac … {1}{T})}$$
$e_s$ is saturated water vapour pressure as function of $T$ in Pascals
$T$ is the temperature in Kelvins
So, the saturated water vapour pressure at $T=0°C=273K$ is equal to $e_s(273K)=610 Pa …

Why are mornings cooler than nights?
In the night there is only cooling of Earth, so the temperature is falling steadily until the Sun is high enough that it balances the cooling. This happens at a point of a minimum temperature. … On graph:
So, the temperature is falling over night after the sunset, but rises again after the sunrise. Thus, the temperature is at its lowest point in the morning. …

How to calculate rate of change of temperature with pressure in Earth's troposhere?
Wow, @John came with a simple answer.
Our goal is to find
$$\frac{dT}{dP}=\frac{dT}{dz}\cdot\frac{dz}{dP}$$
By the equation for pressure lapse:
$$P=P_0\cdot e^{-\frac{z}{H}}$$
where $H=8 km=8000 m$ (s …
