Unit 2 Lesson 6 States of matter
How are plasmas similar to gases, and how are they different?
Plasmas, like gases, have a volume and shape that are varied instead of fixed. However, plasmas are made of charged particles that conduct electricity, while gases are not.
Why can gases be compressed easily?
The large amount of space between gas particles makes it easy to compress gases.
Examine the statement. Gases are easily compressible, but other states of matter are not. Which statement best helps to explain the statement above?
Their particles are more spread out than the particles of the other states.
Write the three common states of matter in the order of greatest particle motion to least amount of particle motion.
gases > liquids > solids
Write the three common states of matter in the order of greatest volume to least amount of volume
gases > liquids > solids
Select the answer choices that describe where plasmas can be found. (Select all that apply.)
in stars in lightbulbs in lightning
Match each of the states of matter to the correct description of its properties.
solids made up of particles; have a fixed shape and a variable volume liquids made up of particles; have a variable shape and a fixed volume gases made up of particles; have a variable shape and a variable volume plasmas made up of charged particles; have a variable shape and a variable volume
Write the three common states of matter in the order of greatest amount of density to least amount of density
solids > liquids > gases
How do liquids differ from gases when they are transferred from one container to a container of a different size?
The volume of a liquid stays the same when it is transferred from one container to a container of a different size, but the volume of a gas expands or contracts.
Examine the statements below and choose the one that correctly states and describes the relationship between volume and density within the states of matter.
They have an indirect relationship, so when the density for a state of matter increases, its volume decreases.
Review the list of items. air, lightning, paper, water vapor, soda, neon lights, milk, ice Correctly match each item with its state of matter: solid, liquid, gas, or plasma.
solid—paper and ice liquid—soda and milk gas—air and water vapor plasma—lightning and neon lights
Describe the shape and volume for the following states of matter: solid, liquid, and gas.
solid—volume is fixed, and shape is fixed liquid—volume is fixed, and shape varies gas—volume varies, and shape varies
