Chemistry: Chapter 1 Matter and Measurement
Terms in this set (33)
one of the three temperature scales in which water freezes at 0° C and boils at 100° C.
those properties that determine how a substance can be converted to another substance by a chemical reaction
Study of matter, its composition, properties and transformations.
a pure substance formed by chemically combining two or more elements
a term that converts a quantity in one unit to a quantity in another unit
a unit of volume equal to one millimeter; one cubic centimeter = 1 cm³ = 1 cc
a physical property that relates the mass of a substance to its volume. Density = g/(mL or cc).
a pure substance that cannot be broken down into simpler substance by a chemical reaction.
english system of measurement
a system of measurement used primarily in the united states in which units are not systematically related to each other and require memorization.
a number that results from counting objects or is part of a definition.
a method of using conversion factors to convert a quantity in one unit to a quantity in another unit
one of three temperature scales in which water freezes at 32° F and boils at 212° F.
a state of matter that has no definite shape or volume. The particles of a gas move randomly and are separated by a distance much larger than their size.
the basic unit of mass in the metric system.
a number that results from a measurement or observation and contains some uncertainty.
a temperature scale commonly used by scientists. The kelvin scale is divided into kelvins (K=°C+273)
a state of matter that has a definite volume, but takes on the shape of the container it occupies. The particles of a liquid are close together but they can randomly move past each other.
the basic unit of volume in the metric system.
a measure of the amount of matter in an object
Anything that has mass and takes up volume
A unit used to measure length.
A measurement system in which each type of measurement has a base unit and all other units are related to the base unit by a prefix that indicates if the unit is larger or smaller than the base unit.
matter composed of more than one component.
those properties of a substance that can be observed or measured without changing the composition of the material.
a substance that contains a single component, and has a constant composition regardless of the sample size.
a system in which numbers are written as y x 10×, where y is a number and 1 and 10 and x can be either positive or negative.
the international system of units formally adopted as the uniform system of units for the sciences.
all of the digits in a measured number, including one estimated digit.
a state of matter that has a definite shape and volume. The particles of a solid lie close together, and are arranged in a regular three-dimensional array.
a unitless quantity that compares the density of a substance with the density of water at 4° C.
states of matter
the form in which most matter exits, gas, liquid, and solid.
a measure of how hot or cold an object is.
the force that matter feels due to gravity.
