CHEM 1150 Lecture Notes - Kinect, Model Theory, Acronym
Scientific approach:
Observations: facts or quantitative data that needs some explanation
○
Hypothesis: tentative proposal that explains observation(s)
Revise if experiment doesn't support
§
○
Experiment: procedure to test hypothesis
Measures one or more variables at a time
§
○
Model (theory): predicts the observation occurs based on the
experimental results
Revise if predictions do not support
§
○
Further experiment: test predictions based on model
Acronym for study guide: Our (Observation) House (Hypothesis)
Expects (Experiment--> possibly revise hypothesis) Money (Model/
theory) Forever[optional] (further experiment)
§
○
-
Chemistry: study of matter and its properties, both macroscopic as well as the
atomic, subatomic, and molecular levels
-
Chemists seek to understand the composition of matter, the changes that
matter undergoes, as well as the energy associated w/ these changes
-
4 states of matter:
Solid
○
Liquid
○
Gas
Are compressible
§
○
Plasma: ionized gas, most common of all phases in the universe
Found in plasma TVs to project the image, in neon signs, sun, stars
§
○
-
The importance of energy in studying matter
Energy: the ability to do work
○
Kinect: due to motion of an object
○
Potential: due to position of object or energy from chemical reaction
Protons and electrons being attracted to each other
Stable if proton and electron touching/ being attracted to
each other
□
Unstable is p and e far apart
