Scientist who do experiments to learn more about the world
What is pure science?
100
Anything that has mass and takes up space.
What is matter?
100
Matter is made up of atoms and molecules and they act like tiny particles that are always in motion.
What is the kinetic theory?
100
liquids resistance to flow
What is viscosity?
100
Density when mass is 25 grams and volume is 5 mL.
What is 5 g/mL.
200
Explanation of why something happens
What is theory?
200
A molecule that contains two or more elements that are chemically combined.
What is a compund?
200
A measure of the average kinetic energy of the particles in an object.
What is temperature?
200
P 1 V 1 = P 2 V 2
What is Boyles Law?
200
the variables in Charles Law
What is temperature and volume?
300
The application of science for pratical purposes
What is technology?
300
A combination of substances that are not chemically combined.
What is a mixture?
300
thermal energy
What is the total kinetic energy?
300
variables affected by the behavoir of gases
What is temperature, volume, and pressure
300
Exactness!
What is precision?
400
A factor that changes in an experiment in order to test a hypothesis.
What is a variable?
400
Properties such as hardness, density, and strength.
What is a physical property?
400
Change from a solid directly into a gas
What is sublimation?
400
fill containers, spread out easily, compressible, low densities, mix well with one another, and expand to fill containers
What are gases?
400
The buoyant force on an object in a fluid is an upward force equal to the weight of the fluid the object displaces
What is Archimedes' principle?
500
Describes a process in nature that can be tested by repeated experiments.
What is a law?
500
the capacity of a substance to combine with another substance
What is reactivity?
500
Change of state from a gas to a liquid
What is condensation?
500
The pressure of a gas increases as the temperature increases, if the volume of the gas does not change. The pressure decreases as the temperature decreases.
What is Gay Lussac's Law?
500
The step in the scienctific method after you form a hypothesis.
