When gases, liquids and solids are heated, they expand. As they cool, they contract or get smaller. The expansion of the gases and liquids is because the particles are moving around very fast when they are heated and are able to move further apart so they take up more room. If the gas or liquid is heated in a closed … See more 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 and gases. All matter is made of tiny … See more At higher temperatures, particles have more energy. Some of this energy can be transmitted to other particles that are at a lower temperature. For example, in the gas state, when a fast … See more 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 … See more 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 … See more WebHow heat energy can travel through a solid In a solid, the particles vibrate around fixed positions. As you heat a solid, these vibrations get larger and larger so that neighbouring particles 'bump' into each other, transferring the vibrations. This is called conduction of heat. hiller lawn care
