Final

Question 1

Why Do We Burn Things For Energy

Answer 1

When electron bonds are broken (burned) they release energy

Question 2

What Makes Oil So Good To Burn

Answer 2

Most Efficiency For Lowest Weight
Efficiency = most hydrogen per carbon

Question 3

What Happens When There Is An Oil Spill

Answer 3

*Oil is less dense than water so floats across the surface (diffusion) making cleaning it hard
*Because of its toxicity and weight it slows down, sinks and poisons sea creatures
*When it sinks it is congealed on the seafloor and combines with the sand making it take a long time to be removed
*i wish i could put these into mini flashcards because it is way too long

Question 4

Solar Panels

Answer 4

Advantages: sort of a passive booster, sun has a lot of energy
Disadvantages: Take a lot of space, arent THAT good,
not very portable

Question 12

Closed Universe

Answer 12

The theory (The GAME Theory) that the universe will come to a halt and close back towards itself creating a new big bang (this is the hot ending)

Question 13

Flat Universe

Answer 13

The “theory” that the universe is on a flat plane witch will expand forever (we hate this one but brendan was “required by law to teach it” or some bs)

Question 14

Galaxies

Answer 14

Shape and catagory are the result of their mass and spin

As it gets more mass it will create a black hole which will make it spin faster resulting in a spiral or barred spiral
