The physical world around us behaves as it does partly because it’s made of a huge number of tiny molecules, each behaving rando
eduard
1. Weird things like the one described above do not happen on a ramdom basis becuause molecules usually move within any enclosure in a ramdom manner. Thus, it is not possible for some types of particles to aggregate in one point while other types of molecule aggreagate in another point. Based on the kinetic energy that is available for each particle, each particle will move random
through the available space, colliding with one another and with the wall of container.

2. It will be a difficult thing to live in a Maxwell' demon world because, things will happen unpredictably and one will never know what to expect next because anything can happen at anytime. For instance, if one is drinking a glass of water, some of the particles of the water may just decide to aggregate to one part of the cup and start boiling. So, for someone who is taking a glass of water, the water may start boiling right inside his mouth when he is drinking, that will be a bad experience. When one is driving a car, the petrol particles may just decide to freeze up when one is busy speeding on the highway; that can cause a very serious accident. Thus, a world where the Maxwell law operates will be a chaotic world.

The vapor pressure of water at 65oC is 187.54 mmHg. What is the vapor pressure of a ethylene glycol (CH2(OH)CH2(OH)) solution ma
Pavlova-9 [17]

Answer:

173.83 mmHg is the vapor pressure of a ethylene glycol solution.

Explanation:

Vapor pressure of water at 65 °C=p_o= 187.54 mmHg

Vapor pressure of the solution at 65 °C= p_s

The relative lowering of vapor pressure of solution in which non volatile solute is dissolved is equal to mole fraction of solute in the solution.

Mass of ethylene glycol = 22.37 g

Mass of water in a solution = 82.21 g

Moles of water=n_1=\frac{82.21 g}{18 g/mol}=4.5672 mol

Moles of ethylene glycol=n_2=\frac{22.37 g}{62.07 g/mol}=0.3603 mol

\frac{p_o-p_s}{p_o}=\frac{n_2}{n_1+n_2}

\frac{187.54 mmHg-p_s}{187.54 mmHg}=\frac{0.3603 mol}{0.3603 mol+4.5672 mol}

p_s=173.83 mmHg

173.83 mmHg is the vapor pressure of a ethylene glycol solution.

According of Dalton's law of Partial pressure, the total pressure of a mixture of gases is the sum of the partial pressures of the individual vases in the mixture.

Hence;

The for hydrogen collected over water, we have a mixture of hydrogen gas and water vapour.

Total pressure = pressure of hydrogen gas + vapour pressure of water

Pressure of hydrogen gas = Total pressure - vapour pressure of water

Pressure of hydrogen gas = 636 mmHg - 28.3 mmHg

Pressure of hydrogen gas = 607.7 mmHg
