A state of matter about heat
Answer (1)
A state of matter is affected by heat in the following ways:Heat increases the energy of the particles in a substance, causing them to vibrate or move faster.In solids, particles are closely packed and vibrate in place; when heated, solids expand slightly because the particles vibratè more but remain close.In liquids, particles are more loosely connected and move around each other; heating causes liquids to expand more than solids as particles move farther apart.In gases, particles are very loosely held and move freely; heating gases causes a significant expansion as particles move faster and occupy more space.When enough heat is added, matter can change its state — for example, solids can melt into liquids, and liquids can evaporate into gases.Conversely, cooling removes heat energy and causes matter to contract or change into a lower energy state (e.g., gas to liquid, liquid to solid).
