Answer:
Diffusion
Explanation:
Diffusion is the movement of a substance (majorly liquids and gases) from a region of high concentration to a region of low concentration. Liquid and gases excluding solids can undergo diffusion because of their ability to move randomly. Diffusion is driven by a gradient in concentration.
For example gases can easily diffuse quickly and easily into another gas, because of its ability to move randomly. The foul air from the back room (higher concentration) was able to quickly spread into the clean air at the front row (low concentration) by diffusion

Answer:
B. Sucking chest wound
Explanation:
A sucking chest wound occurs when a hole, of the size of a coin, is created in the chest cavity that protects the lungs, resulting in the collapse of the lung. Such hole can be created from injuries that involve the puncturing of the chest cavity by foreign objects such as from gunshot, stabs etc. When the lung becomes collapse as a result of a puncture in the chest cavity, the individual would try hard to suck for air while breathing. As the individual breathes in and out, hissing or sucking sound can be heard. Coughing out of blood may be observed too.
