100
Mass is defined by how many of these are in a given volume.
What are particles (matter/atoms/molecules)?
100
The answer is volume.
What is the amount of space an object takes up?
100
The formula for calculating density.
What is mass/volume?
100
In this state molecules are tightly packed and ordered. They vibrate but do not move freely.
What is solid?
100
a piece of wood is cut in half.
What is physical change?
200
Mass does not change based on....
What is gravity?
200
The instrument used to measure volume.
What is a graduated cylinder?
200
When an object is suspended in water
What is neutral buoyancy?
200
In this state molecules move more freely, but take the shape of their container.
What is a liquid?
200
The wick burning on a candle.
What is chemical change?
300
The instrument used to calculate mass.
What is a triple beam balance?
300
The formula for calculating volume.
What is mass/density?
300
The unit used to measure density.
What is g/mL or g/cm3
300
Doing this will increase the volume and cause molecules to move faster.
What is add heat (energy)?
300
lemon juice is added to milk.
What is chemical change?
400
The unit used to measure mass.
What is grams?
400
The units in which volume is measured.
What is milliliters (liters)?
400
If an object floats, this is its density compared to water.
What is less dense?
400
Doing this can cause molecules to slow down and become more dense.
What is cool (decrease energy)?
400
a mixture of salt is added to water.
What is physical change?
500
The formula for calculating mass.
What is density x volume?
500
This can change the volume of a substance.
What is change in temperature?
500
An object that sinks has a density that is ___________ than water.
What is greater?
500
It determines how molecules in a substance move.
What is temperature?
500
wax drippings from a burned candle.
What is physical change.
