What is a chemical change?
300
A more scientific way of saying, "freezing."
What is solidification?
300
This type of change begins with one set of properties and ends with a different set of properties.
What is a chemical change? (Since the substance ends as something different than what it began as.)
300
This type of variable is what is measured in an experiment.
What is a dependent variable?
