What are the two main effects of heat on the state of matter? When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation). What are the three effects of heating? When a substance is heated, […]
What is SonarQube branch analysis?
What is SonarQube branch analysis? This branch is usually known within a development team as “master” or “head” and is analyzed when no specific branch parameters are provided. SonarQube labels this branch as Main Branch, and, with Community Edition, this is the only branch you can analyze. How do you analyze a branch? Then, all […]

Did Einstein believe in a static universe?
Did Einstein believe in a static universe? Summary: Albert Einstein accepted the modern cosmological view that the universe is expanding long after many of his contemporaries. Until 1931, physicist Albert Einstein believed that the universe was static. The change in Einstein’s viewpoint, in fact, resulted from a tortuous thought process. Is our universe static? That […]
How do vectors work?
How do vectors work? A vector describes a movement from one point to another. A vector quantity has both direction and magnitude (size). A scalar quantity has only magnitude. A negative vector has the same magnitude but the opposite direction. Vector is the same as travelling backwards down the vector. Where vectors are used in […]
Where do tropical air masses come from?
Where do tropical air masses come from? Maritime tropical air masses originate over the warm waters of the tropics and Gulf of Mexico, where heat and moisture are transferred to the overlying air from the waters below. The northward movement of tropical air masses transports warm moist air into the United States, increasing the potential […]

Are solar panels bad for your health?
Are solar panels bad for your health? Understand the Safety Issues. As the State of Oregon reports, solar panels are safe and beneficial because they don’t produce harmful greenhouse gases or toxic air that some other energy sources emit. Do solar panels increase your property taxes? One of the most common questions is if installing […]
Why do turbine casings need to be cooled?
Why do turbine casings need to be cooled? The large surplus of air cools the hot sections of the engine to acceptable temperatures ranging from 1,500° to 2,100 °F. Because of the effect of cooling, the temperatures of the outside of the case are considerably less than those encountered within the engine. How hot does […]
