# data[].attributes.body
the tendency of matter to change its shape, area, and volume in response to a change in temperature

# data[].attributes.body
the transition of a substance directly from the solid to the gas phase

# data[].attributes.body
the amount of energy that must be added to a liquid substance, to transform a quantity of that substance into a gas

# data[].attributes.body
the temperature at which a liquid changes to a gas

# data[].attributes.body
the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure

# data[].attributes.body
the temperature at which a given solid will melt

# data[].attributes.body
the body of theory which explains the physical properties of matter in terms of the motions of its constituent particles

# data[].attributes.body
a quantity expressing the magnitude of internal friction

# data[].attributes.body
changes affecting the form of a chemical substance, but not its chemical composition

# data[].attributes.body
when a substance combines with another to form a new substance

# data[].attributes.body
properties that can be observed or measured without changing the composition of matter

# data[].attributes.body
any quality that can be established only by changing a substance's chemical identity

# data[].attributes.body
a state of matter in which an ionized gaseous substance becomes highly electrically conductive

# data[].attributes.body

# data[].attributes.body
a stable subatomic particle with a charge of negative electricity

# data[].attributes.body
a sample of matter that conforms to the shape of a container in which it is held

# data[].attributes.body
a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge

precisely 1/12 the mass of an atom of carbon-12

# data[].attributes.body
the number of protons in the nucleus of an atom

# data[].attributes.body
any of a number of subatomic particles carrying a fractional electric charge

# data[].attributes.body
It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes

# data[].attributes.body
the total number of protons and neutrons in a nucleus

# data[].attributes.body
the force exerted on a body by gravity

# data[].attributes.body
a subatomic particle of about the same mass as a proton but without an electric charge

# data[].attributes.body
the amount of space that a substance or object occupies

# data[].attributes.body
degree of consistency measured by the quantity of mass per unit volume

# data[].attributes.body
Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied
