true or false? to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thor
faltersainse [42]

The thorax is a very vital and important organ in the human body.

  • It is a structure that serves as a<u> </u><u>protective covering</u> for organs in the body such as<u> the lungs, the heart, some vital blood vessels</u> e.t.c

It is<u> false</u> that to <em>make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.</em>

  • When a person breathes in,  <u>the chest cavity expands (the volume increases) and the pressure in the thorax decreases.</u>

  • When a person breathes out, <u>the chest cavity decreases in size, and the pressure in the thorax increases. </u>

  • Therefore, we can see that the <u>process of breathing in humans</u>, follows the <u>principle of Boyle's Law.</u>

  • Boyle's law states that as the<u> volume increases there is a decrease in pressure</u> and <u>as the volume decrease there is an increase in pressure. </u>

Therefore, It is <u>false</u> that to <em>make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.</em>

A solution of chloroform (CHCl3) and acetone((CH3)2CO) exhibits a negative deviation from Raoult's law. This result implies that
Korolek [52]

Answer:

The answer is W. chloroform-chloroform and acetone-acetone interactions are stronger than chloroform-acetone interactions. This is because the bond between acetone-acetone is a dipole-dipole interactions and chloroform-chloroform dipole-dipole compared to the weaker hydrogen-bonding between acetone-chloroform.

It turns out that this hydrogen-bonding happens to be stronger the original dipole-dipole forces, so this shows NEGATIVE DEVIATION from Raoult's law.

Stuart is studying weather data for his region. The data was gathered from 1950 to 2016. Which observation would provide the STR
marusya05 [52]

Answer:

A

Explanation:

The climate of a region is determined through the observation of weather patterns over a long time- usually at least 15 years-  in a region. Studying climate change would therefore also take very long time as meteorologists attempt to perceive changes in these weather patterns. In this case 30 years can be enough to notice a significant increase in rainfall patterns which can be classified as climate change.
