Water-saturated sandy layers became liquified by the ground shaking. Which of the following can trigger a landslide? The concept of surface tension is usually introduced as a force per unit length originated from the "stress tensor" at the liquid surface (and vaguely extended to solids). Stop & Think Questions: Why did the sequential additions of surfactant change this lung system?
For a given volume of a liquid, a sphere has the least surface area. However, if surface molecules could be displaced slightly outward from the surface, they would be attracted back by the nearby molecules. In a bilateral paralysis, the patient may require ventilatory support such as non-invasive positive ventilation, or, in more severe cases, intubation and invasive ventilation. Cohesion, adhesion, and surface tension of water and how they relate to hydrogen bonding. Which of the following has the steepest angle of repose?

Which Of The Following Statements About Surface Tension Is False Regarding
The alveoli pick up the incoming energy (oxygen) you breathe in and release the outgoing waste product (carbon dioxide) you exhale. What anatomical structure connects the stomach and the mouth? The accumulation of rocks at the base of a cliff is called _______. Which of the following statements is false? Surface tension is the phenomenon that occurs at the molecular level. Dry debris forms steeper slopes than water-saturated debris. Enzymes are destroyed during chemical reactions. A slow slide of unconsolidated material that travels as a unit is called ______.
Surface tension may be expressed, therefore, in units of energy (joules) per unit area (square metres). Water can encourage mass flow by: reducing friction between grains. 07275 joule per square metre at 20 °C (68 °F).
Which Of The Following Statements About Surface Tension Is False Answer
You can find forecasts online for the following: On days when the air quality index (AQI) is at an unhealthy range, keep your exposure minimal by keeping doors and windows closed and circulating air inside. The affected side of the diaphragm moves upwards during inspiration, and downwards during expiration. Which of the following slopes is least stable? Cohesive forces cause the water molecules to stick together with a lot of elasticity, allowing the water to function very much like a rubber balloon so that when it is filled with air it doesn't break and simply forms a blanket over the air pocket.
Surface tension depends mainly upon the forces of attraction between the particles within the given liquid and also upon the gas, solid, or liquid in contact with it. A pneumothorax can lead electasisThe addition of surfactant to the lung creased airflowOpening the valve in the side of the glass bell mulated this activity, a pneumothorax automatically followed electasisThe best way to rapidly reinflate a person's collapsed lung is air out of the intrapleural space to recreate negative pressure. Just curious(10 votes). Volcanic eruptions trigger melting of ice and snow. How do geologists classify mass movements? About alveoli cells. Try it nowCreate an account. You correctly answered: b. Mudflows contain large amounts of water.
Which Of The Following Statements About Surface Tension Is False About The Process
The water molecules are more strongly attracted to the glass than they are to other water molecules (because glass molecules are even more polar than water molecules). The curved surface of the water in the capillary tube is called the meniscus. Be aware of days when outdoor air pollution is high. The fourth option says that the surface tension is dependent on the length and not on the area which is correct from what we have discussed earlier that the surface tension is the force per unit length.
In a unilateral diaphragmatic paralysis, patients usually do not require ventilatory support, unless they already have significant lung disease or are symptomatic. All of these slopes have the same stability. The left lungs lose its fuction, because the pressure of intrapleural space and of intrapulmonary are equal, so the pressure. Note: The surface tension is dependent on the force and length and immediately one may think it is a vector quantity because of the force. This dome-like shape forms due to the water molecules' cohesive properties, or their tendency to stick to one another. Cold water will adhere to a glass container more than hot water, because I think the water molecules are moving around more slowly when they're cold and are therefore more able to stick to the glass than the faster moving hot ones. As the lungs are held against the inner thoracic wall by the pleural seal, they also undergo an increase in volume. A slope with loose material saturated with water. Course Hero member to access this document. In the cross section above of the upper part of the Grand Canyon, units B and D are most likely composed of ________. PhysioEX Chapter 7 exercise 3] PEX-07-03.
The larger branches in each lobe are called bronchi. However, because they are exposed to air on one side, they will have fewer neighboring water molecules to bond with, and will form stronger bonds with the neighbors they do have. 31A, Udyog Vihar, Sector 18, Gurugram, Haryana, 122015. Thus, the lung volume will expand 200 milliliters every time the transpulmonary pressure increases 1 centimeter of water. Your answer: c. The lung will remain collapsed. Learn about surfactants in the lungs, surfactant function, what produces surfactant, and how this helps alveolar surface tension. This is why the water rises to different heights in capillary tubes made of different materials (substances).

Which of the following rock types forms the steepest slopes? The characteristic slope of a pile of dry sand is called the ______. This upward motion against gravity, known as capillary action, depends on the attraction between water molecules and the glass walls of the tube (adhesion), as well as on interactions between water molecules (cohesion). Although tiny, the alveoli are the center of your respiratory system's gas exchange. Mudflows tend to move slower than debris flows. Course Hero uses AI to attempt to automatically extract content from documents to surface to you and others so you can study better, e. g., in search results, to enrich docs, and more. Because of this property, certain insects can stand on the surface of water. Mas movement deposits are destroyed by large animals.
It is initiated by relaxation of the inspiratory muscles: - Diaphragm – relaxes to return to its resting position, reducing the superior/inferior dimension of the thoracic cavity. As it moves through blood vessels (capillaries) in the alveoli walls, your blood takes the oxygen from the alveoli and gives off carbon dioxide to the alveoli. Solved by ramonistry. Use an air cleaner or purifier at work or at home to reduce indoor dust and fumes. It is stated in the video in this section called Surface Tension and in the last paragraph of this article.
