What is carbohydrates.
100
This is acid deposition.
What is acid rain/snow/fog.
100
This is how fossil fuels are formed.
What is organic material (dead things) are covered quickly with sediment (so there is no oxygen for decomposition) and crushed by intense heat and pressure over hundreds of millions of years.

1) This kind of energy is used to fry eggs.
2) This kind of energy is found in eggs.
What is 1) thermal; 2) chemical/potential
200
This is the product of photosynthesis that is a "food."
What is glucose/sugar.
200
This type of fat is good for you, avoiding heart disease.
What is unsaturated fat.
200
These two chemicals cause acid rain/deposition.
What is sulfur oxides and nitrogen oxides.

What state is crude oil, how is it refined, where is it found?
What is liquid, distillation, in reservoir rock.
300
When a rollercoaster cart accelerates down the track hill, it shows this.
What is an energy conversion (from potential to kinetic).
300
This is the name of a system that changes energy from one form to another.
What is a converter.
300
These three factors can affect metabolism.
What is
- time of day
- age
- exercise
- fitness

Coal is burned to create thermal energy to heat water to steam which turns the turbines (what energy is this) of a generator to make electricity.
What is kinetic energy.
300
These are the two ways that coal is mined.
What is coal quarries (open-pit mining) and networks of underground rooms/tunnels.
400
When a pendulum is swinging, this is when its potential energy is the greatest.
What is when it's at the top of its swing.
400
The sum of all chemical reactions in the body is this.
What is metabolism.
400
Saturated fats can be found in this, unsaturated fats can be found in this, trans fats can be found in this.
What is meat, vegetable oils and nuts, processed foods (fries, chips).
400
These are the four steps in how a nuclear, solar, or coal-fired generator works.
What is 1) nuclear/solar/coal-fired energy heats up water; 2) water turns to steam; 3) steam turns the turbine; 4) turbine is connected to generator (rotating coil in a magnetic field) which makes electricity; 5) electricity sent to homes.
400
A lightbulb uses 180 joules in 3 seconds, this is its power.
Power = energy / time
What is 60 watts.
500
This natural process in nature uses solar energy in a direct way.
What is photosynthesis.
500
This is the formula for cellular respiration.
What is
glucose + oxygen --> carbon dioxide + water + energy
500
The difference between malnourished and undernourished is this.
What is missing nutrients vs missing calories.
500
These are the three fossil fuels.
What is coal, oil, natural gas.

A toaster takes in 1200 joules of energy and produces 600 joules of useful energy. This is its % efficiency.
% efficiency = (useful output energy / total input energy) x 100%
