<h2>Answer : Option C) Smaller volume - crowded particles - more collisions - high pressure</h2><h3>Explanation : </h3>

The kinetic molecular theory of gases explains that if there is small volume of gas there will be more crowding of the gas molecules inside the container. The crowded gas molecules will collide with each other and also with the walls of container as a result, exchange of energies will take place. Which will increase the pressure inside the container, and will raise the pressure than the initial pressure.

a sample of fully saturated clay weighs 1350 g in its natural state and 975 g after drying. what is the natural water content of
svetoff [14.1K]

Answer:

The soil has a percentage of water by mass of 27.8 %.

Explanation:

Keeping in mind that

  • Mass of Clay = Mass of water + Mass of Dry Soil

we can <u>calculate the mass of water</u>:

  • 1350 g = Mass of Water + 975 g
  • Mass of Water = 375 g

We can then <u>calculate the mass percentage of water in the soil</u>:

  • 375 / 1350 * 100% = 27.8 %

2.5 moles of a gas is enclosed in a 87.2 L cylinder with a moveable piston at 425 K and 1.0 atm. An additional 2.5 moles of gas
Nesterboy [21]

Answer:

112 L

Explanation:

Since the pressure is being held constant, you can use the following variation of the Ideal Gas Law to find the new volume:

\frac{V_1}{T_1N_1}=\frac{V_2}{T_2N_2}

In this equation, "V₁", "T₁", and "N₁" represent the initial volume, temperature, and moles. "V₂", "T₂", and "N₂" represent the final volume, temperature, and moles.

V₁ = 87.2 L                             V₂ = ? L

T₁ = 425 K                              T₂ = 273 K

N₁ = 2.5 moles                       N₂ = 2.5 + 2.5 = 5.0 moles

\frac{V_1}{T_1N_1}=\frac{V_2}{T_2N_2}                                                   <----- Formula

\frac{87.2 L}{(425K)(2.5 moles)}=\frac{V_2}{(273 K)(5.0 moles)}                    <----- Insert values

\frac{87.2 L}{1062.5}=\frac{V_2}{1365}                                                    <----- Simplify denominators

0.08207=\frac{V_2}{1365}                                                 <----- Simplify left side

112L={V_2}                                                        <----- Multiply both sides by 1365
