Theories, such as Dalton's Atomic Theory or the Kinetic Molecular Theory of Gases have which of the following in common?

A sample is found to be slightly compressible and has a definite volume, but indefinite shape. The sample is most likely a
liquid

An example of a chemcial change is
burning gasoline

Boyle's Law is an example of
an indirect mathematical relationship between two variables (pressure and volume)

Choose the state of water in which the water molecules are farthest apart on average.
steam (vapor)

Theories, such as Dalton's Atomic Theory or the Kinetic Molecular Theory of Gases have which of the following in common?
both explain and predict observed phenomena

While an object is falling to the ground, its potential energy due to location is decreasing.
True

When elements combine to form compounds, those compounds have the properties that are completely different from those of the elements from which they were made.
True

Charles' Law states that the volume of a given amount of gas will increase if the temperature of the gas is increased.
True

The element potassium (K) is a good conductor of electricity and is malleable.
True

All gases have fairly low densities.
True

When milk goes "sour", only a physical change has occured.
False

The particles in a solid do not move at all.
False

The main focus of applied research is to gain greater understanding of how the natural world operates.
False

False
