Chapter 2, Quiz 2 Flashcards
The state of matter in which particles vibrate in fixed positions, giving a substance a fixed shape and volume
Solid
The state of matter in which particles are close together but able to move around
Liquid
The state of matter in which particles are far apart, move rapidly, and have little interaction with each other
Gas
A gas-like state of matter, formed at very high temperatures, that consists of high-energy ions and free electrons
Plasma
Anything about a substance that can be observed or measured without altering its chemical composition
Physical Property
Any change in matter that does not alter its chemical or nuclear composition
Physical Change
A change that alters the chemical composition of a substance
Chemical Change
A property of a substance that describes how its chemical identity changes in the presence of another substance or under certain conditions
Chemical Property
The change of state from a solid to a liquid
Melting
The temperature at which a solid turns to a liquid
Melting Point
The change of state from a liquid to a solid
Freezing
The change of state from a liquid to a gas (vapor)
Vaporization
The relatively slow form of vaporization in which a liquid particles obtain sufficient energy to change the gaseous state through the random collisions of particles
Evaporation
The relatively fast form of vaporization in which the energy within a liquid creates higher pressure within the liquid than the air pressure outside the liquid
Boiling
The temperature at which a liquid starts to boil
Boiling Point
