AnswerAmontons's law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. ... If the gas volume is decreased, the container wall area decreases and the molecule-wall collision frequency increases, both of which increase the pressure exerted by the gas (Figure 1).:

The ideal gas constant is a proportionality constant that is added to the ideal gas law to account for pressure (P), volume (V), moles of gas (n), and temperature (T) (R). R, the global gas constant, is 8.314 J/K-1 mol-1.
According to the Ideal Gas Law, a gas's pressure, volume, and temperature may all be compared based on its density or mole value.
The Ideal Gas Law has two fundamental formulas.
PV = nRT, PM = dRT.
P = Atmospheric Pressure
V = Liters of Volume
n = Present Gas Mole Number
R = 0.0821atmLmoL K, the Ideal Gas Law Constant.
T = Kelvin-degree temperature
M stands for Molar Mass of the Gas in grams Mol d for Gas Density in gL.

Answer:
6.04 hr
Explanation:
The bus first travels a distance of 210 km south at an average velocity of 85 km/h. The time, t it takes to cover this distance is gotten from d = vt and t = d/v where d = distance and v = velocity.
So, t = 210 km/85 km/h = 2.47 h
The bus then stops for 25 min. We convert 25 min to hours by dividing by 60.
So 25 min = 25/60 hr = 5/12 h = 0.42 h
The bus then travels 230 km south at an average velocity of 73 km/h.
The time it takes to cover this distance is t = 230 km/73 km/h = 3.15 h
So, the total time for the trip is the sum of each individual time, which is 2.47 h + 0.42 h + 3.15 h = 6.04 hr
So, it takes 6.04 hr for the total trip
