Chem 105 Freeman Test 1 with correct answers 100% 2026 What is Chemistry? - Correct Answer Chemistry is the study of matter and the changes it can undergo What is Matter? - Correct Answer Matter is anything that has mass and occupies space. Anything we can see, barring shadows, is matter. What are the steps of the Scientific Method? - Correct Answer Observation, Hypothesis, Experiments, Publication, Conformation, Application What are the Physical Sciences? - Correct Answer Geology, Astronomy, Physics, and Chemistry What are Biological Sciences? - Correct Answer Botany, Zoology Basic Science - Correct Answer Research without the goal of a practical application Applied Science - Correct Answer Research with well defined, short term goals for a specific problem Technological Science - Correct Answer Application of science for industrial application. This is when something already exists in science but we find a was to use it for us. Macroscopic - Correct Answer Large enough to be seen with the naked eye Microscopic - Correct Answer Seen only with the aid of a microscope Submicroscopic - Correct Answer Can only be observed indirectly, such as atoms or subatomic particles. Mass - Correct Answer The amount of quantity of matter in an object; doesn't change with location Weight - Correct Answer The force that results from the attraction between matter and the Earth; changes based on location Intensive Properties - Correct Answer Properties that are independent of the amount of the sample; concentration, density, color, boiling point Extensive Properties - Correct Answer Properties that are dependent on the size of the sample such as mass, volume, or energy Elements - Correct Answer A pure substance consisting of only one kind of atom, and can not be decomposed into simpler substances by normal chemical means Atoms - Correct Answer Smallest unit of an element Pure Substance - Correct Answer Matter with fixed composition at the submicroscopic level Chemical Compounds - Correct Answer Pure substances composed of atoms of different elements combined in definite, fixed ratios. These can be decomposed into simpler substances or elements by chemical means. Ex. H2O is a pure substance but not an element Homogeneous Mixtures - Correct Answer Mixtures that are uniform in composition, such as milk Heterogeneous Mixtures - Correct Answer Mixtures that are not uniform in composition Solution - Correct Answer Homogeneous mixtures of different compounds combined in such a way that the composition is uniform throughout Chemical Properties - Correct Answer Properties that result in a chemical reaction, converting the identity of one of more substance, such as flammability, biodegradability Physical Properties - Correct Answer properties that can be observed or measured without changing the identity of the substance, such as boiling point,
