what is an independent variable

• the variable that doesn't change

• the variable that does change

• the variable that is impacted by the change

• the variable that stays the same

What is an experiment control?

• normal conditions

• the independent variable

• limiting factor

• what you learn after the experiment is over

What is a constant in an experiment?

• normal conditions

• variables that don't change

• variables that do change

• the same variables

What does volume measure?

• it's not defined for a solid

• it's measured in kilograms

• the amount of matter

• the amount of space matter takes up

What does mass measure?

• the milliliters in a beaker

• the centimeters on a meter stick

• how much matter there is

• how much space matter takes up

What does density measure?

• the mass divided by the volume of a substance

• its' a physical property of a substance

• the volume divided by the mass of a substance

• how many particles are in a baloon

Which equations are used to measure density? m = mass; v = volume; d = density

• m = d/v

• d = m/v

• m = d x v

• v = m/d

What are the units of measure for density?

• g/ml

• ml/g

• g/cm³

• ml

choose the pH values for a substance considered an acid

• 7

• 2

• 8

• 4
