Answer the question below:   Devon's cat, Fluffy, is looking for a nice warm spot to lay out in the sun. Because of how the sun heats the earth, and how some heat radiates into the air, the cat laying high up in a tree branch, rather than on the ground, would keep the cat cooler or warmer?    Assuming that:  The surface is heated by the Sun and some of that heat radiates back into the air. This makes the temperature higher near the surface than at higher altitudes.
cooler

Answer the question below:   Mary melts a 1 pound chocolate bar and 1 pound of chocolate chips in two pots. Which melts first bar or chips?

Maybe you could make hot chocolate from some smaller pieces like chocolate chips, but it is much easier to add a powder to your milk. This is because the smaller the pieces are, the more surface area they have.
