Heat, Kinetic Energy and Temperature

SCI 110

The study of heat relate to Kinetic theory of matter is that universe is made up of matter and energy. Matter is made up of atoms and molecules. Atoms and molecules are always in motion because energy. Energy forces them to contact into each other or vibrate back and forth. When this happens molecules and atoms creates a form of energy called (heat) thermal energy, which is present in all matter. (“Matter”2009) Molecules interact, attracting each other through a force of cohesion. There five phases of matter. Liquid, solid, and gases are three commons phases of matter. The two others are Plasmas and Bose-Einstein Condensates. Plasma is hot, ionized gases. Plasma is formed under extremely high energy that molecules are rippled apart and only free atoms exist. Bose-Einstein condensates were first seen in 1995. Satyendra Nath Bose and Albert Einstein predicted its existence in 1920. B-E condensates are gases super fluids cooled to temperature near absolute zero. Atoms attains its same quantum- mechanical state and can float pass others without friction. (“Matter states matter” 2004) The three major phase change are solid-liquid, liquid- gas and solid-gas. These phase changes can go into either direction. (Tillery, Enger, Ross 2009) (p89) To get a better understanding we must define what kinetic theory states and what does heats mean in relation to the theory. According to (Tillery, Enger, & Ross 2009) it defines Kinetic theory of matters as the collection of assumptions that all matters is made up of tiny atoms and molecules that interact physically, that explains the various states of matter and that have an average kinetic energy that defines the temperatures of a substance. (p720-21) Many early Greek philosophers believed substances are...
