The amount of Space a substances takes up
Volume
How do you find the volume of cubes and/or rectangular prisms?
Volume = length x width x height
What axis is the bottom line of a line graph?
X-axis
What are the units of measurement for length, mass, volume, and temperature?

The amount of matter in an object
Mass
What is the formula to convert Celsius to Kelvin?
K = C + 273
What axis is on the side of the graph?

Where do you find the volume of a liquid using a graduated cylinder, beaker, or a flask?
By reading the line closest to the bottom of the meniscus.
The average kinetic energy of molecules in a substance
Temperature
What is the equation for calculating percent error?
Measured value x accepted value/accepted value x 100
What is a dependent variable?
The variable that changes in response to the independent variable
Explain the six steps of the water displacement method.
Step 1: Pour any amount of water in a container that can measure volume.
Step 2: Record the initial volume.
Step 3: Place object in glassware.
Step 4: Look and see how much the water level rose.
Step 5: Record the final volume.
Step 6: Subtract the initial volume from the final volume and the difference is the amount of space the object takes up, also known as the object’s volume.
How much mass is located in a specific volume of space
Density
What is an independent variable?
The variable being manipulated
What unit of temperature is typically used in science?
Celsius or Kelvin
