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 nodule is a spot on the lung, seen on an X-ray or computed tomography (CT) scan. In fact, a nodule shows up on about one in every 500 chest X-rays. Normal lung tissue surrounds this small round or oval solid overgrowth of tissue. It may be a single or solitary pulmonary nodule. Or, you may have multiple nodules. Your lung nodule is more likely to be benign if: 1  You are younger than age 40. 2  You are a nonsmoker. 3  There is calcium in the nodule. 4  The nodule is small.
