Chapter 7.1: Matter and Its Properties Flashcards
- differentiate the states of matter using shape and volume - explain the movement of particles in solids, liquids, and gases - differentiate between physical and chemical properties - calculate density, manipulate formula of density to calculate for mass or volume - understand how properties of a substance can be used to identify a substance
What is the definition of volume?
The amount of space a sample of matter occupies.
A state of matter with a definite shape and volume is called?
Solid.
A state of matter with a definite volume but not a definite shape is called?
Liquid.
A state of matter without a definite shape or a definite volume is called?
Gas.
Solids have a definite shape but not a definite volume, true or false?
False. They have both a definite shape and volume.
Orange juice is an example of which type of state of matter?
Liquid.
Deodorant spray is an example of which state of matter?
Gas.
A Toyota land cruiser is an example of which state of matter?
Solid.
Particles move the most in gases and least in solids, true or false?
True.
Particles in solids can only vibrate. True or false?
True.
How do particles move in a liquid?
The particles can move and slide past each other.
How do particles move in a gas?
They move freely in all directions.Particles on a solid have a strong attraction force. True or false?
Do particles in a gas have attractive forces?
No because they are so far apart.
Mass and weight are the same thing, true or false?
False. Mass is the amount of matter in an object and is measured in kilograms. Weight depends on gravity so can change and is measured in Newtons.
What is the definition of mass?
Mass is the amount of matter in an object and is measured in kilograms.
