What does the particle arrangement of a liquid look like?
Particles of a liquid are not packed as closely together as a solid. They are not fixed in place.
Refer to page 51 for an image.
What is a liquid?
A state of matter that has no definite shape but has a definite volume.
What is the formula for density?
D= m/v
What does the particle arrangement of a gas look like?
Particles of a gas are widely spaced and and collide with one another.
Refer to page 53 for an image.
What is volume?
The amount of space that matter occupies
What is temperature?
How hot or cold something is
What is a compound?
a substance made up of two or more elements chemically combined in a specific ratio
What is matter?
Anything that has mass and takes up space.
What is mass?
A measure of how much matter is in an object.
What is condensation?
What does boiling point mean?
The temperature at which a liquid boils.
What is an atom?
The basic particle from which all elements are made
What is surface tension?
the result of of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together
What is a substance?
A single kind of matter that is pure and has a specific set of properties.
What is thermal energy?
The total kinetic and potential energy of all the particles of an object.
What is a physical change? Give an example of a physical change.
A physical change alters the form or appearance of matter but does not turn any substance in the matter into a different substance.
Example: chopping wood
What happens during filtration?
During filtration, a substance is passed through some kind of filter that allows fine particles to pass through while filtering out larger particles.
A physical property is a characteristic of a pure substance that can be observed without changing it into another substance.
Example: Gold - has a high luster, and a distinctive color.
Wood- is hard and inflexible
What is a chemical change? What is an example of a chemical change?
A chemical change is a change in matter that produces one or more substances.
Example: burning wood
What is a chemical property? What are some examples of chemical properties?
characteristics that describe something's ability to become something else.
Example: if iron is exposed to air and water, it will rust.
What is the density of a piece of gold with a mass of 284 g and a volume of 14.7 cm?
19.3 g/cm
What is the formula for work?
How much work is done when 300 N of force is used to lift a a dog 1.5 m?
Work=Force x Distance
Work = 300 x 1.5
Work = 450 N-m
What is sublimation?
The change in state from a solid directly to a gas without passing through the liquid state.
What is the formula for kinetic energy?
1/2 x Mass x Speed2

Particles of solids
vibrate in place, are packed very closely together, and have a definite shape and volume.
