This tool is used to measure the volume of irregular objects and liquids.

What is a graduated cylinder?

200

In this type of change, the particles take on, or absorb, energy. 

What is an endothermic change?  

200

This phase change happens when a substance goes from a solid state to a gas state.

This tool is one used to measure mass.

What is a triple beam balance?

300

Temperature is a measure of this kind of energy.

What is thermal energy?

300

This phase change occurs when a substance's temperature decreases as it goes from a liquid to a solid.

What is freezing?

These are what is manipulated by the experimenter in an experiment.

What are independent variables?

500

This measurement of a regular solid is taken by dividing the mass of this object by the result of multiplying three sides together, also referred to as the volume.

What is density?
