Answer: Option (C) is the correct answer.
Explanation:
Movement of particles in a substance is responsible for change in state of the substance or matter.
This means that more is the motion of particles more will be their kinetic energy.
Also, kinetic energy is directly proportional to temperature.
K.E = 
So, less is the temperature of an object or substance less will be be the motion of its particles. Therefore, molecules will come closer to each other and state of substance will change from liquid to solid.
Thus, we can conclude that the motion of the molecules would decrease at a molecular level if a liquid is placed in cool conditions.
C. Tripling the length and reducing the radius by a factor of 2 is the change to a pipe would increase the conductance by a factor of 12.
<u>Explanation:</u>
As we know that the resistance is directly proportional to the length of the pipe and it is inversely proportional to the cross sectional area of the pipe.
So it is represented as,
R∝ l /A [ area is radius square]
So k is the proportionality constant used.
R = kl/A
Conductance is the inverse of resistance, so it is given as,
C= 1/R.
R₁ = kl₁ / A₁
R₂ = kl₂/A₂
R₂/R₁ = 1/12 [∵ conductance is the inverse of resistance]
= l₂A₁ / l₁A₂
If we chose l₁/l₂= 3 and A₂/A₁= 4 So R₂/R₁= 1/3×4 = 1/12
So tripling the length and reducing the radius by a factor of 2 would increase the conductance by a factor of 12.
The acid/base pair that give equivalence point that Cannot be predicted by general knowledge is NaOH and HCI ONH.
<h3>What is an Acid and base?</h3>
An Acid is a substances that is corrosive in nature and turn blue lithmus paper to red which it react with base to produce salt and water.
Acid dissolve metals.
Base is a substance that turn red lihthmus paper to blue and react with acid to produce salt and water.
Therefore, The acid/base pair that give equivalence point that Cannot be predicted by general knowledge is NaOH and HCI ONH.

Answer:
the sun is the smallest object in our Solar System
Explanation:
Answer:
Explanation:
Hello.
In this case, we can solve this problem by applying the Boyle's law which allows us to understand the pressure-volume behavior as a directly proportional relationship:
In such away, knowing the both the initial pressure and volume and the final volume, we can compute the final pressure as shown below:
Consider that the given initial pressure is also equal to Pa:
Which stands for a pressure increase when volume decreases.
Regards.
