Condensation occurs when a gas loses energy and comes together to form a liquid, according to the U.S. Geological Survey. Buffers can do this because they consist of a combination of a weak acid and a corresponding weak base. A) the density of dark matter was slightly higher than average when the universe was very young. It is basically the type of substance which is formed when liquid converts into . B) matter that may inhabit dark areas of the cosmos where we see nothing at all D) Dark matter probably does not really exist, and rather indicates a fundamental problem in our understanding of gravity. A balloon filled with hydrogen gas explodes upon contact with a spark. Yet, many of us are stuck following an ingrained system that's actually working against us and making communication harder. Inertia is the tendency of the matter to be in a state of rest or motion. The reaction is called a dehydration synthesis, in which the H from the glycerol's alcohol group and the OH from the fatty acid's acid group are removed as water. 3.

Matter is a general term describing any 'physical substance'. an R group. The left reaction is endergonic, and the right reaction is exergonic. In a gas, the particles have a great deal of space between them and have high kinetic energy. They are all generally unreactive elements. It will take the shape of its container. Home / Uncategorized / which of the following is not a form of matter. No, because there would no longer be a difference in electronegativity between the oxygen and hydrogen atoms.
