Answer:

1.The pleural cavity aids optimal functioning of the lugs during breathing. It transmits movements of the chest wall to the lungs, particularly during heavy breathing. The closely approved chest wall transmits pressures to the visceral pleural surface and hence to the lung (10-19.

2.The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarge.

tangare [24]

Answer:

There are more earthquakes on the West coast of the United States, because the boundaries of the North American, Pacific, and Juan de Fuca tectonic plates are located there. As the edges of the plates slide past or are forced under each other, the movement creates earthquakes

Does the size of the particles change as a substance changes state
Kazeer [188]
Ok, particle is not a very nice word, no real sense of size associated with it
it can be a group of molecules like a speck of sand
referring to the molecules themselves
or refering to the atoms that make up the molecule

now in terms of phase change,
if we consider a speck- a group of molecules- then solids will expand when heated, however this definition falls flat in terms of phase change

ok, how about molecules, as molecules undergo phase change, the molecules in relation to each other will move apart from one another. Solid- molecules are bonded, Liquids- molecules are close and flow around each other, Gas- molecules are a significant distance from one another. But the increase in size when you heat up a molecule, i would have to say yes. adding heat increases energy which increases molecular vibration which would probably  increase the overall average size to some unnoticeable degree.

now standalone atoms are just atoms, if you want to consider the electron cloud as size, then heating it up would negligibly cause the outer move outward. but it really depends on the scale of the question
