WebEnergy is an international, multi-disciplinary journal in energy engineering and research. The journal aims to be a leading peer-reviewed platform and an authoritative source of information for analyses, reviews and evaluations related to energy. The journal covers research in mechanical engineering and thermal sciences, with a strong focus on ... All heat energy, including heat generated by fire, is transferred in different ways: Convection transfers heat energy through gases and liquids. As air is heated, the particles gain heat energy allowing them to move faster and further apart, carrying the heat energy with them. Warm air is less dense than cold air and … Ver más Matter is all around you. It is everything in the universe – anything that has both mass and volumeand takes up space is matter. Matter exists in different physical forms – solids, liquids … Ver más At higher temperatures, particles have more energy. Some of this energy can be transmitted to other particles that are at a lower temperature. … Ver más When gases, liquids and solids are heated, they expand. As they cool, they contract or get smaller. The expansion of the gases and liquids … Ver más Faster moving particles ‘excite’ nearby particles. If heated sufficiently, the movement of particles in a solid increases and overcomes the bonds that hold the particles together. The substance changes its state from a solid to … Ver más
