Question | Answer |
---|---|
Matter | anything that has mass and takes up space. |
Volume | a measure of the size of a body or a region in three‐dimensional space. |
Meniscus | the curve of a liquid's surface by which one measures the volume of the liquid. |
Mass | a measure of the amount of matter in an object or substance. |
Weight | a measure of the gravitational force exerted on an object; its value can change depending on its location in the universe |
graduated cylinder | usually a long cylinder made of glass or plastic that is used to measure the volume of a liquid. |
beaker | a large mouth container resembling a cup usually used to measure volumes of liquid greater than 100 milliliters. |
cubic | three‐dimensional |
inertia | the tendency of an object/substance to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the object. |
physical property | a characteristic of a substance that does not involve a chemical change, such as density, color, or hardness. |
density | the ratio of the mass of a substance to the volume of the substance, how closely packed are the particles of matter in an object/substance. |
thermal conductivity | the rate at which a substance transfers heat. |
physical state | the form in which a substance exist, such as solid, liquid, gas, or plasma. |
solubility | the ability of a substance to dissolve in another substance, such as Kool‐Aid™ dissolving in water. |
ductility | the ability of a substance to be pulled into a wire. |
malleability | the ability of a substance to be rolled or pounded into thin sheets. |
physical change | a change of matter from one form to another without a change in the substance's identity. |
chemical property | a property of matter that describes a substance's ability to participate in chemical reactions. |
flammability | the ability of a substance to burn. |
reactivity | the ability of two or more substances to combine and form one or more new substances. |
characteristic property | physical or chemical properties that always exist for substance |
chemical change | a change that occurs when one or more substances change into entirely new substances (new identities) with different properties. |
composition | the type of matter and arrangement of particles in an object. |
electrolysis | a process that passes electricity through water in an effort to split hydrogen and oxygen atoms apart from each other. |
