Updated 2026 Questions and Answers
100% Verified Exam Prep and Comprehensive
Rationales Included
, Solid to Liquid Melting (absorbs energy)
Liquid to Solid Freezing, (releases energy)
Liquid to Gas vaporization/absorbs energy
Gast to Liquid condensation/ release energy
Gas to Solid deposition/ release energy
Solid to Gas sublimation
Matter Anything that takes up space
Mass the amount of matter in an object
How Does Matter Change? Matter usually changes state when you add or take away heat, which changes the
temperature of the matter
Substance A single kind of matter that is pure and has a specific set of properties.
examples of substances 1. Water
2. Alcohol
3. Oil
4. Food coloring
Solids The particles in solids are tightly packed
Liquids Liquids are also a condensed phase, however, in contrast to solids, the particles
have some translational kinetic energy, which means they have freedom to move
gas phase the phase of matter in which atoms or molecules can move essentially
independently of one another
Which state(s) of matter take the shape of their container? Liquids and gases take the shape of their containers since, they do not have
definite shape and volume. Only solids have definite shape and volume.
