2. The substance can change state. For example, if the substance is ice, it can melt into water. Perhaps surprisingly, this change does not cause a raise in temperature. The moment before melting the average kinetic energy of the ice molecules is the same as the average kinetic energy of the water molecules a moment after melting. Although heat is absorbed by this change of state, the absorbed energy is not used to speed up the molecules.
A lung infection is an inflammation in or around the lung tissues that is caused by a virus, fungi, or bacteria. There are a number of things that can trigger this sort of problem, but the four most common tend to be asthma, bronchitis, pneumonia, and tuberculosis.uberculosis. Tuberculosis is one of the most serious lung diseases a person can get. It is a serious pulmonary infection that is caused by mycobacterium tuberculosis. The lungs are usually the main organ affected, but the infection can and often does spread.
Pneumonia is any disease that causes inflammation of the lung tissue, particularly the air sacs (alveoli) of the lung.It is a fairly common respiratory disease that can be life threatening.neumonia is any disease that causes inflammation of the lung tissue, particularly the air sacs (alveoli) of the lung.
