States of Matter
Which state of matter has a definite shape and a definite volume?
Solid
What tool is used to measure the mass of an object?
Balance
What property describes whether an object is attracted to a magnet?
Magnetism
What does it mean when a substance is soluble in water?
It can dissolve in water.
Which is a physical property: color, mass, texture, or all of the above?
All of the above
Which state of matter takes the shape of its container but keeps the same volume?
Liquid
What tool is used to measure the volume of a liquid?
Graduated cylinder
Which object would most likely be attracted to a magnet: a plastic spoon, wooden pencil, iron nail, or glass cup?
Iron nail
Which substance is most likely soluble in water: salt, sand, pebbles, or plastic?
Salt
Which physical property tells how much matter is in an object?
Mass
Which state of matter spreads out to fill its container?
Gas
What metric unit would you most likely use to measure the mass of a small rock?
Grams (g)
Name one metal that can be attracted to a magnet.
Iron, nickel, steel or cobalt
A student adds sugar to water and stirs. The sugar is no longer visible. What happened?
The sugar dissolved.
Which physical property describes the amount of space an object takes up?
Volume
A student pours water from a cup into a bowl. What property of liquids is demonstrated?
A liquid takes the shape of its container.
A graduated cylinder contains 25 mL of water. After a rock is placed inside, the water rises to 32 mL. What is the volume of the rock?
7 mL
A student tests a plastic ruler, steel paper clip, wooden pencil, and glass marble with a magnet. Which object would most likely be attracted?
Steel paper clip
A student puts sand into water and stirs. The sand settles at the bottom. Is sand soluble in water?
No, sand is not soluble in water.
Scientists observe that an object is silver, smooth, hard, and magnetic. Are these physical properties?
Yes
Ice, liquid water, and water vapor are all made of the same substance. What changes when water changes state?
The arrangement and movement of the particles change.
Two objects have the same volume, but Object A has more mass than Object B. Which object is more dense?
Object A
True or False: All metals are magnetic.
False
Powder A disappears when placed in water. Powder B settles at the bottom. What can the student conclude?
Powder A is soluble, and Powder B is insoluble in water.
A student measures an object's mass and volume, observes its color and texture, tests its magnetism, and tests whether it dissolves in water. Why are these tests useful?
They provide evidence that helps scientists identify, classify, compare, and describe the object's physical properties.
