Gibbs free energy of a reaction (
Δ
G ) is the change in free energy of a system that undergoes the chemical reaction. It is the energy associated with the reaction, which is available to do some useful work. If ΔG<0
, then the reaction can be utilized to do some useful work. If
ΔG>0
, then work has to be done on the system or external energy is required to make the reaction happen. ΔG=0 when the reaction is at equilibrium and there is no net change taking place in the system.
The Cascades rain shadow can be described as such: ocean-influenced moist air masses are forced to rise when they meet the tall moun- tains. The rising air cools, condenses, and the moisture falls as precipitation. On the leeward (dry) side of the mountain, the now dry air warms and sinks.
They have a sea of delocalised electrons which are free to move therefore they can carry a current
Explanation:
The amount of moisture present in air at a given temperature is known as humidity.
Whereas relative humidity is the amount of percentage of moisture it contains when compared to the maximum moisture it can contain at a given temperature.
Also % Relative humidity (RH) =
where, P = the partial pressure of water vapour
= the equilibrium vapor pressure at a particular temperature.
Accrding to the Clausius-Clapeyron equation, decreases with decrease in temperature.
Hence, it means that at super-cooled conditions the %RH would be 100%.
On the other hand, the temperature will be very high at super-heated conditions.
Hence, will be high hence %RH will be low.
It is also known that at saturated condition, P =
Therefore, %RH is 100.
Thus, we can conclude that when the relative humidity is 90%, we say the air is humid.
