Homogenous matter - Study guides, Class notes & Summaries

Chemistry definition : Study of structure, properties, transformations of matter Matter : Anything that has mass + takes up space Phases: solid, liquid, gas Condensed phases = solids + liquids Intermolecular Forces (IMF) : = Interactions between molecules/atoms/ions Solution : = Homogenous mixtures of 2+ pure substances In a solution, the solute is dispersed uniformly throughout the solvent - Solute = compound(s) in lesser amount - Solvent = compound in greater amount 2 | P a g e E...

us knowledge. To be termed scientific, a method of inquiry is commonly based on empirical or measurable evidence subject to specific principles of reasoning Experiments - answera procedure carried out to refute or validate a hypothesis. They help students understand the cause- and - effect relationship by demonstrating what outcomes occur when a particular factor is manipulated independent variable - answerelement manipulated in the experiment dependent variable - answerwhat the scientist...

Characteristics of Quantitative Research numerical data (quantity); hypothesis & research procedure are stated BEFORE data collection; large sample size; rely on statistical procedure; low interaction with subjects; rely on controlling, measuring, and generalizing; objective by nature Quantitative Methods/Designs survey research; correlational research; causal comparative; experimental; single subject experimental Sampling techniques for quantitative research simple random; stra...

How can matter be classified? Matter: Purity: 1. Pure Substances A. Elements B. Compounds 2. Mixtures A. Homogenous Solutions B. Heterogenous Solutions

how do scientists make observations Scientists are naturally curious about the world. Thoughts are taken note of and further investigated Steps of scientific inquiry -Make an Observation -Form a Question -Form a Hypothesis -Conduct Experiment -Analyze the Data and Draw Conclusions What is a hypothesis an informed guess as to the possible answer. Can be used for further scientific investigation Controls/constants unchanged. Used as base for comparison of variables Variable/experim...
