(Solution) C165 OA – Everything that tested in the OA

WGU 2025 C165 – These are all that were in the OA

Observational – uncontrolled, not in lab       Theory – statement explaining observations Hypothesis – testable statement Law – supported by evidence, repeat experiments Elastic – goes back to original shape             Inelastic – sticks together

Compound – chemical w/ different types of atoms            Element/Pure – 1 atom WATER IS A MOLECULE, A CHEMICAL COMPOUND

Mixture – combo of pure substances (salt water) Gravitational – Increases with mass/height Elastic – Stretched springs, rubber bands

Chem – Chem bonds in a subst, foods/fuels

Thermal – Motions of atoms/molecules (temp)

Kinetic – any moving object, more mass=more energy

Mech Waves – (Longitudinal Waves like Sound Waves) Travel faster NO VACUUM

Electro Wave – (Transv) – Gamma, Xray, UV, Vis Light, Infrared, Microwave, Radio Wave VACUUM Microwav – cell phone, Ultraviolet – Sterilization,
