What happens when ice melts? What does it turn into and what chemical process does it undergo? It's for a science project, not school or anything, just on my own. I know hydrogen peroxide turns into water if you leave it in the sun, but if you leave an ice cube in the sun it melts down and it's not solid anymore... I'm confused..?
Introduction. A pulmonary embolism is a blockage in the pulmonary artery, the blood vessel that carries blood from the heart to the lungs. This blockage â usually a blood clot â is potentially life-threatening because it can prevent blood from reaching your lungs. pulmonary embolism is a blockage in the pulmonary artery, the blood vessel that carries blood from the heart to the lungs.

A collapsed lung occurs when the air behind a thick mucous plug in the bronchial tubes gets absorbed. Once this occurs there is only a finite time (1-3 days) to re-expand the lung, otherwise it can get infected and could possibly stay permanently collapsed.n most cases, the patient needs to be placed in a way that the collapsed lung is on top to facilitate drainage. This is combined with aggressive chest physiotherapy and encouragement to cough frequently to re-expand the collapsed lung tissue. Deep breathing exercises are also part of the therapy.
