100 degrees

Temperature at which water boils (Celcius)

0 degrees

Temperature at which water freezes (Celcius)

0 degrees

Absolute Zero (Kelvin)

Accuracy

Getting close to the right answer

Presicion

Consistently getting a specific answer

Line Graphs

Can show relationships where the DV changes due to changes in the IV, often shows changes over time

X axis

Horizontal axis, always the IV

Y axis

Vertical Axis, always the DV

Solubility Curve

Shows how much of a substance will dissolve in 100 mL of water at a given temp

Bar Graph

Good for comparing multiple things and info gathered by counting

Pie Chart

Used to show how a fixed quantity is broken up, shows percentages

The motion of molecules

What is the Kelvin System Based on?

An educated guess

Hypothesis

A hypothesis proven to be true by a lot of evidence

Theory

Independent Variable

The variable that can be changed by the controller of the experiment

Dependent Variable

The variable that is measured in an experiment

Control Variables

The variables that are kept consistent to achieve accurate results
