Describe the 3 ways in which heat is transferred and provide an example for each?
What is Conduction is transferred through direct contact, like a spoon in hot soup. Convection occurs when heat is transferred through the movement of warmed air and liquid, like pasta boiling in water, and radiation occurs when electromagnetic waves travel through empty space, like the sun heating the earth.

Petroleum replaced coal as the nations leading source of energy, however only 1/3 of petroleum is produced in the US. Why is this a problem and how can it be solved?
What is since we demand 20 million barrels of petroleum a day, we have to rely on other nations for petroleum and prices often flucuate and this effects American's because gas prices have increased. We can buy energy efficient cars that use electricity.

Rily and Oliva are having a discussion about how a cake is baked. Rily thinks that the cake is baked through conduction, since the cake is sitting on the rack in the oven,however Olivia thinks that its through radiation, since the heat is coming from the coils on the bottom of the oven? Who is correct?
What is they are both right. The thermal energy is traveling through the coils to heat the racks that are in direct contact with the cake pan.
