Gned 1101 Final Question and answer
100% correct 2025
5-step Method - correct answer ✔1.Observation
2.Question
3.Hypothesis
4.Experiment
5. Evaluation
Hypothesis - correct answer ✔Educated guess, must have a variable that
can be proven true or false, must be innovated- has 3 variables: dependent,
independent, cofounded
theory - correct answer ✔isn't false, but has been disproven by testing or
replication
2 types of observation - correct answer ✔1. Qualitative- not proven true- fake
science
2. Quantitative- real science- proven true and backed up with data
What makes up the universe - correct answer ✔Energy and Matter
What process releases bond energy - correct answer ✔Combustion
Combustion - correct answer ✔breakdown of 2 particles that release energy.
Chemical reaction that causes energy to be released.
, Whats in an atom - correct answer ✔proton, electron, neutron
Mass defect - correct answer ✔the difference between the mass of an
isotope and mass number- when you don't have equity
Energy- Mass Equivalence - correct answer ✔e=mc2-- rest mass energy of
an object
Sources of Energy - correct answer ✔1.coal
2.wind
3.solar
4.hydro
5.geothermal
6.biofuels
7.oil
8. natural gas
9. nuclear
Conservation of Energy - correct answer ✔energy cannot be created or
destroyed, it may be transformed, but the total amount never changes
Radioactivity - correct answer ✔a steady but unpredictable process, found in
the nucleus of an atom and fakes place entirely
Bq - correct answer ✔the activity of a quantity of radioactive material that
decays in which one nucleus per second
Relative time vs Absolute Time - correct answer ✔r= chronostratic
