It’s the beginning of the summer and things are starting to get hot in your house. You don’t want to have to rely on an air conditioning system to cool your house because you know how often they break down. How could you design a new home to keep it as cool as possible without air conditioning? Moving to the Arctic is not an option. Give two examples of something that you could do for each type of energy transfer that would help to cool off your house. You can draw a sketch to help describe your adjustments just be sure to label things.

Which notation is used to represent an alpha particle? a. b. c. d.

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

The diagram shows a boulder rolling down a hill into a valley and then up the opposite hill. at which position does the boulder have the greatest kinetic energy? a b c d
