Physical and Chemical properties
A property that is observed with senses and determined without destroying matter
What is a physical property
matter with no definite volume and no definite shape.
what is gas
In this state of matter, particles move in straight lines until they collide with something.
what is gas
define Kinetic Energy
what is the energy an object has due to its motion
a) the change of state from a gas to a liquid
b) is energy added or removed?
a) Condensation
b) removed
indicates how a substance reacts with something else and how matter is changed into a new substance after the reaction
What is a chemical property
high-energy matter consisting of positively and negatively charged particles
what is plasma
Mass is:
what is the amount of matter in an object
____________ is the total potential and kinetic energy of an object
What is thermal energy
a) change in state in gas becomes solid without first becoming liquid
b) is energy added or removed?
a) what is deposition
b)energy is removed
Name the following physical property:
A straight piece of wire is coiled to form a spring.
What is Ductility
a measurement of a liquid’s resistance to flow.
what is viscosity
Define density
what is mass per unit volume
How can you change an object’s state of matter?
by adding or removing thermal energy
If thermal energy is removed from a liquid, the following change occurs
what is freezing
Physical or chemical change:
You forgot to dry the bread knife when you washed it and reddish brown spots appeared on it.
chemical change
matter with a definite volume, but no definite shape.
what is liquid
It's matter has a definite volume but no definite shape.
what is liquid
temperature at which matter changes from liquid to solid
what is freezing point
a) solid becomes gas without first changing to liquid
b) is energy added or removed
a) what is sublimation
b) energy is added
Malleability, ductility, change in state, density, color, shape, luster etc
the uneven forces acting on the particles on a liquid’s surface.
what is surface tension
the positively charged parts of atoms
what is a proton
measure of the average kinetic energy of all the particles in an object
what is temperature
If thermal energy is added to a solid, the following change occurs:
What is melting
name 3 chemical properties
flammability, reactivity, toxicity, combustion, oxidation, pH Level
the gas state of a substance that is a solid or liquid at room temperature.
what is vapor
In this state of matter, the distance between the particles is so great there is little or no attraction between them.
what is gas
vaporization that occurs only at the surface of a liquid
what is evaporation
If thermal energy is added to a liquid, the following change occurs:
In baking biscuits and other quick breads, the baking powder reacts to release carbon dioxide bubbles. The carbon dioxide bubbles cause the dough to rise.
What type of change occurs in the case above and what phrase tells you this is correct:
Chemical change.
baking powder reacts to release carbon dioxide bubbles
matter with a definite volume and a definite shape
What is solid
the negatively charged parts of atoms
what is 'electrons'
________ is stored energy resulting from the interactions between particles or objects
what is potential energy
two types of vaporization
What is evaporation and boiling
