Matter Unit 1

You can determine an object's mass by using a

• gradulated cylinder

• spring scale

• balance

• potato

What type of changes observe the law of conservation of mass?

• only changes of state

• only physical changes

• only chemical changes

• both physical and chemical changes

Temperature will

• increase during a change of state

• decrease during a change of state

• increase or decreased depending on the substance

• stay the same during a change of state

Changes of state

• change the identity of a substance

• change the appearance of a substance

• change the mass of a substance

• change the chemical make up of a substance

To find the volume of an irregularly shaped object you would

• use a spring scale

• use a graduated cylinder

• use a triple beam balance

• use a microwave

An example of a homegenous mixture is

• lemonade

• dirt

• concrete

• a snowglobe

An example of a heterogenous mixture is

• lemonade

• water

• concrete

• calcium

What two types of measurements make up DENSITY? 

• Mass and Volume
• Temperature and Mass
• Grams and Centimeters
• Volume and Weight

Why do the liquids form different layers?

• They have different densities.  
• They have different masses.  
• They have different volumes.  
• They are different temperatures.  

If an object has a density of 3.6 g/mL and you put it into water, will it sink or float?  

• sink
• float
