Atoms and Molecules/Order of Magnitude
Atoms
What is thermal energy?
Energy that is related to heat.
What are the three states of matter
Solid, liquid, gas
What is the range pH scale? (What numbers does it go to)
0-14
When do we do cellular respiration?
All the time!
Which is LARGER, an atom or a cell?
Cell
What is an example of an energy transfer?
What state of matter has a fixed VOLUME but not a fixed SHAPE
Liquid
What does a pH indicator tell you?
How acidic or basic something is
What is the name of the type of energy that our cells use?
ATP
What is an example of a molecule?
Water, CO2, O2, C6H12O6, etc.
What is the difference between energy transfer and transformation
Energy transfer is the same energy moving between objects or place. Transformation means the type of energy is changing
What is it called when matter changes from a gas into a liquid?
Condensation
What is an acid base reaction?
It is any acid and any base reacting together.
What type of organisms do cellular respiration?
Plants and animals, anything that uses oxygen
Put the following words in order from SMALLEST to LARGEST
Organ system, organelle, organism, organ
Organelle, Organ, organ system, organism
What is the difference between electric and electromagnetic energy?
Electric is a current of moving electrons, electromagnetic is energy that moves in waves
[see board]
What is the law of conservation of matter?
Matter cannot be created or destroyed
What is the first step of cellular respiration called?
Glycolysis (breaking down glucose/sugar)
What is the name of the three particles that make up an atom and what are their charges?
Proton (+), neutron (0), and electron (-)
What is the full energy transformation from the smoothie bike lab. Person's breakfast --> bike --> blender --> smoothie being eaten
Chemical --> mechanical --> mechanical --> chemical
What happens to the molecules in a substance when HEAT is added
They expand (spread out) and move faster
The law of conservation of matter tells is that what must be true about the amount of atoms at the beginning vs the end of a reaction?
The number of atoms at the beginning and the end must be the same, because matter can't be created or destroyed
What is the formula for cellular respiration?
H2O2 + KI → H2O + O2 + KI
C6H12O6 + O2 → 6CO2 + 6H2O + ATP
6CO2 + 6H2O → C6H12O6 + O2
4. C2H4O2 + NaHCO3 → NaC2H3O2 + H2O +CO2
C6H12O6 + O2 → 6CO2 + 6H2O + ATP
