Draw a model - In the space below draw a model of how the Sun creates energy, what happens to this energy as it
travels to the surface of the Sun, and how this energy travels to Earth. The Sun is a main sequence star that is mostly
hydrogen undergoing nuclear fusion into helium. Your model should contain labels of: hydrogen, helium, gamma rays,
the Sun, the Sun's core, space, the Earth, visible light/UV/infrared radiation and any other labels you need.

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called

When a light bulb shines, it gives off light energy and energy. a. heat b. potential c. chemical d. electrical
