physical property - correct answer. characteristic of a substance observed without
changing it into another substance
solid - correct answer. definite shape and definite volume
liquid - correct answer. definite volume but indefinite shape
gas - correct answer. indefinite shape, indefinite volume
plasma - correct answer. state of matter that occurs when energy such as electricity or
heat is applied to a gas.
mass - correct answer. amount of matter in an object
volume - correct answer. the amount of space an object takes up

weight - correct answer. measure of the pull of gravity on an object
melting/freezing point - correct answer. the temperature at which a substance
changes from a solid to a liquid or a liquid to a solid
boiling point - correct answer. the temperature at which a substance changes from a
liquid to a gas
melting - correct answer. the process of changing from a solid to a liquid
freezing - correct answer. the process of changing from a liquid to a solid
evaporation - correct answer. the process of changing from a liquid to a gas
, condensation - correct answer. the process of changing from a gas back into a liquid
sublimation - correct answer. the process of changing from a solid directly to a gas
without becoming a liquid
