Answer:
a. True
Explanation:
The gases that we study are governed by different laws of physics. Gases behaves according to some given set of laws like the Universal gas laws, Boyles law, Charles law, Gay Lussac's law and many more.
But we do not see a definite pattern or rule when we study solids or liquids. The behavior of the solids and liquids are not described by the set of laws which are applied regardless of the identity of the substance.
Answer:
The desirable characteristic of Barium suspension are:
<u>Thick layering</u>
<u></u>
Explanation:
First know the meaning of the terms :
1. Rapid flow
2. Thick layering
3. Good mucosal adhesion\
1. Rapid flow : The lower the viscosity of the solution , more is its flow in the solution. For example : Honey has more viscosity so it flows slowly . On the other hand water flow faster.
2. Thick layering : layering is the deposition of one layer of the liquid over other. The deposited layer can be of different substance.
3. Mucosal Adhesion : It is the adhesion(attraction) between two materials ,one of which is mucous.It is attractive force between the drug and the mucus inside the body.
Barium suspension:
<em>It is not a Good mucosal adhesion material because of low solubility in water and lipid .</em>
<em>Only those solution are good in adhesion which have higher solubility in water.</em>
It is widely used as the contrast media for the examination of gastrointestinal because of its <u>Thick Layering Property. It has the consistency of thick glass . At room temperature it is called "warm thick milk"</u>

Answer:If a bouncing ball has a total energy of 20 J and a kinetic energy of 5 J, the ball’s potential energy is 15J.
If the kinetic energy of the ball decreases, then the potential energy will Increase.
