Matter (solids/liquids/gases)
What is an example of a solid? (1)chair (2)milk (3)oxygen (4)water
(1) chair ; a chair does not change shape and therefore is known to be a solid.
Which is a type of gas? (1)oxygen (2)water (3)books (4)trees
(1) oxygen; oxygen has atoms that are freely moving and is spread around the earth.
Solids have a definite shape, mass, and volume. (1) true (2) false
(1)True: The atoms of a solid are closely packed together, and do not change shape (stays the same). One example includes a tree.
Which of the following can be compressed? (1)oxygen (2)ice (3)wood (4)an instrument
(1)oxygen: oxygen can be compressed as it is a gas; Gases do not have definite shape or volume.
Gases are like liquids in that it takes the shape of the container it is in. (1)true (2)false
(1)true. One common characteristic between gases and liquids are that both take the shape of the container.
Water can be a solid, liquid, and a gas. (1)true (2)false Explain.
(1)true:water can be heated to become a gas (with atoms spread apart infinitely) or can be cooled to be a solid (an ice cube) or remain a liquid at room temperature.
Which of the following can be compressed, but cannot be spread out infinitely? (1)water (2)oxygen (3)air (4)wood
(1)water; water is a liquid, and a liquid can be compressed, but not spread out infinitely. A gas can only be spread out infinitely.
Liquids do not have atoms (1)true (2)false
(2) false: liquids do have atoms, only the atoms are able to move around. This is why liquids differ from solids.
Air is an example of a liquid. (1)true (2)false
(2)false; air is an example of a gas, since air is able to travel freely. Air is spread across the empty space around the earth
Gases do not have definite volume, but has definite shape. (1)true (2)false
(2)false; gases do not have a definite volume since they take the shape of the container.
Volume is the amount of ___ that matter takes up. (1)matter (2)space (3)mass (4)liquid
(2)space. Volume measures the amount of space that matter takes up.
Which of the following has definite volume? (1)oxygen (2)wood (3)water (4)syrup
(2)wood; wood is a solid, and solids have a definite volume.
Which of the following can NOT be compressed? (1)water (2)air (3)ice (4)water vapor
(3)ice. Ice is a solid form of water, and therefore can NOT be compressed as solids cannot be compressed.
Which of the following are matter? (1)wood (2)water (3)air (4)all of the above
(4) all of the above! Matter is anything that takes up space, and all phases (solid, liquid, and gas) take up space.
What are the properties of matter? (1) shape (2)mass (3)volume) (4)all of the above
(4)all of the above are examples of the properties of matte. Mass is the amount of matter an object has, and volume is the amount of space the matter takes up.
Why are gases different from liquids?
Gases are different from liquids, since the atoms in gas are more spread out and move FREELY. Particles in a liquid are close are thus SLIDE in movement (does not spread out infinitely).
Why can't liquids stay one shape when moved to different containers?
Liquids do not have a definite shape, but they do have a definite volume; thus, they are unable to remain in one shape like a solid can.
Why does milk, a liquid, take the shape of your cup?
Milk will take the shape of any cup it is placed in, as its atoms are loosely packed and are able to move around; Since liquids do not have a definite shape of their own, they will take the shape of their containers.
Can a solid have a definite shape, but indefinite volume?
No; a solid must have definite shape and definite volume to be classified as a solid.
Can a tree be a liquid?
No; a tree is a solid because it has a definite volume and a definite shape.
Can a tree be compressed?
No; solids cannot be compressed as they have a definite shape and a definite volume.
How do gases and solids differ?
Solids have a definite shape and does not conform to the shape of a container. Gases have an indefinite shape and will change shape to fit the shape of the container.
What phase change occurs when an ice cube melts?
The ice cube changes from a solid to a liquid, as the ice cube turns into water. The closely packed particles loosen slightly for the overall phase to become liquid.
Can the air be compressed?
Yes; air can be compressed as it is a gas; Gases do not have definite shape or volume.
Can water be a solid?
Yes; water can be a solid, liquid, and a gas. If water is heated, it will evaporate to become a gas. If water is cooled, it will become solid ice.
