Answer:
Generally, observed behavior that can be formulated into a statement, sometimes mathematical in nature, is called a natural law- D.

Answer:
Well ads I remember, the motion of the gas particles is random and in a straight-line. A sample of gas is contained in a closed rigid cylinder.
And here is what I found too -
According to Kinetic Molecular Theory, gaseous particles are in a state of constant random motion; individual particles move at different speeds, constantly colliding and changing directions. We use velocity to describe the movement of gas particles, thereby taking into account both speed and direction.
Answer:
a. Dew point: 48.7°C. Degrees of superheat 26.3°C
b. 
c. 
Explanation:
a. Based on the psychometric chart of air, the specific volume of air at the given conditions is:

The dew point at the specific volume and the 30%-humidity has a value of 48.7°C, it means that there are 75°C-48.7°C=26.3°C of superheat.
b. At 75°C the molar fraction of water is 11580Pa/101625Pa=0.114 moles per cubic meter of feed gas are:

Once the 35°C are reached, the mole fraction of water is 1688Pa/101325Pa=0.017 and remaining moles per cubic meter of feed gas are:

So the condensed moles per cubic meter of feed gas are:

c. Considering the Raoult's law, one computes the pressure as follows:

At 75°C and 30%-humidity, the saturation water vapor pressure has a value of 38599Pa, thus:
