Order/Design
Why are there laws of nature? (three answers)
no reason, underlying natural principle, intentionally/intelligently designed
What is gravity?
Any object with mass warps the dimensions of space and time around itself
What are the three types of fields?
Electric, magnetic, and gravitational
What are the two configurations that atoms can take when bonding with other atoms?
Molecules and crystals
What is a compound?
Two or more atoms chemically bonded together
What are some examples of evidence for existence of laws of nature?
(answers will vary)
What is electromagnetic force?
Two objects that are near to each other repel each other due to the electrons in their atoms repelling one another
Cause- anything with matter
Affects- anything with mass
What is a molecule?
a chemically bonded cluster of atoms
What is a homogeneous mixture?
A mixture that is the same throughout, completely uniform throughout
Can you give an example of order and structure in nature?
(answers will vary)
What is the strong nuclear force?
It holds the protons together in the nuclei of an atom (grabs them and binds them together)
What causes electric fields? What is affected by an electric field?
cause- any charged object
affect- any charged object
When atoms organize themselves in repeating geometrical structures and patterns called an array...this is also known as?
A crystal lattice
What is a heterogeneous mixture? Give an example
Two or more different substances in a mixture (soil, seasoning, ect)
Can you name one of the necessary conditions for life?
presence of water, distance from the sun, atmosphere traps heat, large moon, magnetic field
What is the weak nuclear force?
The weak nuclear force is the agent behind beta decay
What is Ampere's law?
A magnetic field is produced around any current carrying wire
What is a pure substance?
an element or compound
What is a solute? What is a solvent?
A solute is dissolved into another substance, a solvent is the substance things are dissolved into.
What do Maxwell's equations govern?
electricity and magnetism
Why does nothing ever actually touch anything else?
Force of repulsion- electromagnetic force
What causes a magnetic field? What is affected by it?
cause- magnets/current carrying wires
affected- magnets, current carrying wires, moving charged particles
How is the periodic table organized?
By atomic mass and electronegativity
What happens when something dissolves?
particles in the solute are separating and mixing with the particles of the solvent (review molecular solute or crystalline substance)
