Carbon Monoxide and Carbon Dioxide.
decrease
During evaporation the density increase.
Breathing is act of passing air in and out through nostrils. Respiration is exchange of gases such as taking in oxygen and passing out carbondioxide by every living cell of the body.
During compressive forces, materials experience a decrease in volume and an increase in density due to the inward pressure. In contrast, during tensile forces, materials experience an increase in volume and a decrease in density as they stretch and become thinner.
The rails expand during the heat of a summer day.
oxygen and carbon dioxide
Oxygen and carbon dioxide increase and decrease in the lungs.
When breathing in, or inhaling, the diaphragm contracts, or tightens. When exhaling, or breathing out, the diaphragm expands, or loosens.
During an asthma flare, the airways of the body swell and make inhaling/exhaling very difficult. The movement of air through the swollen airways is what causes the wheezing sound.
it separates the chest cavity from the abdominal cavity. other wise they would e everywhere! please reply to this by saying if it helped and what you thought of it (you can do this by 'improving the answer')
During inhalation, the diaphragm contracts and moves downward, allowing the lungs to expand and fill with air. This creates a vacuum in the chest cavity, drawing air into the lungs. During exhalation, the diaphragm relaxes and moves upward, forcing air out of the lungs.
decrease
During evaporation the density increase.
When inhaling, the muscles work together to increase the size of the chest space, lowering the pressure inside the lungs and drawing air in from outside. Exhaling involves relaxation of the diaphragm and intercostal muscles, reducing the volume of the chest cavity and this, combined with the lungs' natural elasticity, serves to increase the pressure inside the lungs and move air out.
No it should actually increase.
