Answer:
B. The time during which a collision between two molecules occurs is negligibly short compared to the time between collisions
Explanation:
Kinetic molecular theory postulates:-
- The gas is composed of small molecules are they are in continuous random motion and having elastic collisions with one another and also with the walls of the container.
- The molecules of the gas does not exert any kind of repulsive or attractive forces on each other and they their size is negligible as compared to the difference between them.
- Pressure exerted by the molecules of the gas results from the collisions which is happening between the molecules of the gas and the walls of the container.
- Average kinetic energy of molecules of the gas is directly proportional to absolute temperature.
Hence, The correct option is:- <u>B. The time during which a collision between two molecules occurs is negligibly short compared to the time between collisions. This is not an important postulate of the kinetic molecular theory.</u>
Answer:
<em>What is atmospheric pressure? -------> Atmospheric pressure is a force in an area pushed against a surface by the weight of the atmosphere of Earth, a layer of air.</em>
<em>Why does the atmosphere exert pressure? -------> Because gas particles in the air—like particles of all fluids—are constantly moving and bumping into things, so they exert pressure. </em>
<em>What is the value of atmospheric pressure at sea level, in newtons per square centimeter? -------> Atmospheric pressure at sea level is about 10 N/cm2 or 100 kPa or about 10 m of water or about 760 mm of mercury, but varies with the weather, and of course altitude.</em>

Answer:
the equation for cylinders is V = (pi)r2h
none of these are even close but i can do a little more research
sorry if this one wasnt as much help
It breaks small pieces off over time until the rock is absolutely gone.
