States of matter Flashcards
What are the three main states of matter?
Solid, liquid, and gas.
True or False: In a solid, particles are closely packed and vibrate in fixed positions.
True.
Fill in the blank: The state of matter where particles are far apart and move freely is called a __________.
gas.
Which state of matter has a definite shape and volume?
Solid.
What happens to the particles in a liquid when heat is applied?
They gain energy and move faster, potentially turning into a gas.
Multiple Choice: Which state of matter has a fixed volume but no fixed shape? A) Solid B) Liquid C) Gas
B) Liquid.
In which state of matter do particles have the highest kinetic energy?
Gas.
True or False: Gases are compressible because their particles are tightly packed.
False.
What is the process called when a solid turns directly into a gas?
Sublimation.
Fill in the blank: The change from gas to liquid is called __________.
condensation.
What term describes the amount of space a substance occupies?
Volume.
Multiple Choice: Which of the following has the least amount of energy? A) Solid B) Liquid C) Gas
A) Solid.
True or False: Liquids take the shape of their container but maintain a constant volume.
True.
What is the term for the energy required to change a substance from solid to liquid?
Latent heat of fusion.
Fill in the blank: The transition from liquid to solid is known as __________.
freezing.
What happens to the density of a substance when it changes from a liquid to a gas?
The density decreases.
Multiple Choice: Which state of matter has particles that are very far apart and move independently? A) Solid B) Liquid C) Gas
C) Gas.
True or False: All substances can exist in all three states of matter.
True.
What is the term for the process of a gas turning into a solid?
Deposition.
Fill in the blank: The process of a solid becoming a liquid is called __________.
melting.
