Properties of Matter Review

What is the most dense material? Rembeber D=m/v

• Liquid A
• Liquid B
• Liquid C
• Liquid D

What substance would conduct the LEAST amount of heat?

• Concrete
• Glass
• Brick
• Wood

Which of the substances do you think would be a gas based off of the densities you can calculate from the table?
D=m/v

• 1
• 2
• 3
• 4

Maggie is calculating the densities of various substances for a science assignment. She has samples of two different liquids and two solid cubes. She measures the volumes and masses of the liquids and the cubes and records her observations in the table below. 
What can Maggie correctly predict about the relationship between the liquids and the solids? Be aware that the density equation is d =  m/ v, with d being density, m being mass, and v being volume. 

• Cube B will float in Liquid B. 
• Cube A will sink in Liquid A. 
• Cube A will sink in Liquid B. 
• Cube B will float in Liquid A.

Which statement would be true if the 3 liquids were to be put into the same beaker?

• The middle layer should be salad oil. 
• The top layer should be corn syrup. 
• The top layer should be water. 
• The bottom layer should be corn syrup.

A scientists uses a magnet to identify 3 substances, and writes his observations down.  Using his observations, which answer is most correct?
Substance 1 is not effected by the magnet
Substance 2 moves away from the magnet
Substance 3 moves toward the magnet

• Substance not 1 is a metal
• Substance 2 and 3 are both metals
• Substance 2 is a magnet, substance 3 is either a magnet or a metal
• Substance 1, substance 2 and substance 3 are all metals.  

Mineral A can scratch Mineral B, but Mineral B cannot scratch Mineral A. Mineral C can scratch Mineral A. Which of these statements is true? 

• Metal A is the  hardest mineral
• Mineral B is the hardest mineral
• Mineral C is the hardest mineral

What physical property lets you know that it is a bad idea to plug in a electrical devise while standing in water?

• Flammability
• Conductivity
• Solubility
• Melting point

A scientist finds a substance in his lab, not knowing what it is, he runs a few tests on it to determine what it is.  Taking a small portion of it, warms it up to see if it evaporates, but it only heats up.  He hits it with a hammer, and nothing happens to it.  Finaly he adds it to a liquid, and it dissolves.   What physical property allows the substance to dissolve? 

• Malleability
• Conductivity
• Solubility 
• Density

If an object is placed in space, what physical property of that object can change, and what property stays the same?  

• The mass of the object chages, the weight of the object stays the same
• The weight of the object changes, the mass of the object stays the same
• The conductivity of the object stays the same, the flamability of the object stays the same
• Both the weight and the mass of the object changes.
