When pressure is added to a gas the molecules bounce around really fast and push against the walls of its container. That's why when you squeeze an empty water bottle you can crush it all the way. The smaller the container the more the molecules hit the walls faster and that's what creates pressure. While moving around the molecules get hot as they speed up. Heat = Pressure.

Answer:

“The kinetic energy of gas particles is higher in hot food than in cold food.”  

Explanation:

One of the properties responsible for this is “The kinetic energy of gas particles is higher in hot food than in cold food.”  

Remembering that kinetic energy is related to the speed or speed in the movement of particles or molecules, you can start by saying that foods are made up of molecules. The higher the temperature of these foods, the faster the molecules move. If the molecules move fast enough, they detach from food and move in the air. Our noses absorb those molecules, and from that we smell that food. Hot food, as mentioned, has faster molecules, so they come off faster and there is more in the air. Then we can smell that food faster than the cold food molecules.

This process is called diffusion. Diffusion is a process in which particles are introduced into a medium that was initially absent from them, that is, the gradual mixing of the molecules of one gas with the molecules of another, by virtue of their kinetic properties. In this case the particles or molecules of the food are mixed with the particles present in the air, in order to reach our noses and you can feel their smell

Which of the following leads to a higher rate of diffusion?
miv72 [106K]
<h3><u>Answer;</u></h3>

Higher velocity of particles

<h3><u>Explanation;</u></h3>

The diffusion rate is determined by a variety of factors which includes;

  • Temperature such that the higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly and the diffusion rate will be high.
  • Concentration gradient such that the greater the difference in concentration, the quicker the rate of diffusion.
  • Higher velocity of particles increases the diffusion rate as this means more kinetic energy by the particles and hence the particles will mix and move faster, thus higher diffusion rate.

At 100 degrees Celsius, the ion product for pure water is Kw= 51.3*10^-14. What is the pOH of water at this temperature? A) 7.00
Levart [38]

7.86 is the pOH of water at this temperature of 100 degrees celsius.

Option E is the right answer.

Explanation:

Data given:

Kw = 51.3 x 10^{-14}

pOH = ?

we know that pure water is neutral and will have pH pf 7.

The equation for relation between Kw and H+ and OH- ion is given by:

Kw = [H+] [OH-}

here the concentration of H+ ion and OH- ion is equal

so, [H+]= [OH-]

Putting the values in the equation of Kw

pKw = -log[Kw]

pKw = -log [51.3 x 10^{-14}]

pKw = 12.28

since H+ ion OH ion concentration is equal the pH of water is half i.e. 6.14

Now, pOH is calculated by using the equation:

14 = pOH + pH

14- 6.14 = pOH

pOH = 7.86
