Variables: Remember, the three variables: controlled (what is kept the same), independent (what

is tested or changed), and dependent (what is the outcome or observed). List variables below:
Variable For All Trials
Controlled measuring equipment, using the same brand for small and large
amounts
Independent The type of liquid that is being heated
Dependent The boiling point of each liquid

Answer 1

Based on the information provided, here are the variables listed clearly:

• Controlled Variables:

  • Measuring equipment (using the same brand for both small and large amounts)
  • Volume of liquid being heated (ensuring consistent volumes across trials)
  • Heating method (using the same heat source and technique)
  • Environmental conditions (such as pressure and ambient temperature)

• Independent Variable:

  • The type of liquid that is being heated

• Dependent Variable:

  • The boiling point of each liquid

These variables will help ensure a fair test when determining how different liquids behave when heated.
