Imagine that you are a tour guide giving tours of the interior of the sun. Type up the script of your tour narration below. Your tour begins in the middle of the sun and moves outward. In your own words, what are the key facts and concepts for each layer that you want your audience to remember? Make sure to identify each layer by name.

If a simple machine reduces the strength of a force, what must be increased?

Four 5-gram blocks of metal are sitting out in the sun and absorb the same amount of heat energy. use the following specific heat capacity data to determine which block will increase its temperature the most.

In a particular chemical reaction, the energy of the reactants is 30 kj and the energy of the products is 5 kj. 
 the maximum energy of the system is 40 kj. sketch a potential energy diagram for this reaction. make sure to label the energy of the reactants, the energy of the products, the activation energy, and the enthalpy change for the reaction.
