C6H12O6
Glucose
What is the purpose of respiration
to release energy
What is convection
Heat transfer in liquids and gases. This happens when particles gain energy,
move apart and cause the liquid or gas to become less dense and
therefore rise. Cooler liquids/gases take its place
what is conduction
Conduction is when heat is transferred in solids from one particle colliding with each other.
emit
energy is given out
absorb
energy is taken in
What does this word equation mean?
glucose + oxygen -> Carbon Dioxide + water (+energy)
Aerobic respiration
What does this word equation mean?
Glucose -> lactic acid +little energy
Anaerobic respiration
Why are metals good conductors?
because they have free electrons
Some chemicals in cigarettes
Nicotine, Tar, Carbon Monoxide, Arsenic
What is radiation
The process where thermal energy is emitted and/or absorbed through electromagnetic waves.
what happens to particles when they are heated?
The atoms gain energy and vibrate They collide with neighboring atoms and pass energy
What are the effects of exercise
less chance of chronic disease
increasing heart and breath rate
more energy
effects of smoking
lung rot
lung cancer
sroke
smokers cough
