Objectives: After completing this unit, students should be able to:
- Differentiate among the three states of matter: gas, liquid, and solid.
- Distinguish among pure substances, compounds, elements, mixtures, heterogeneous, homogeneous, and solutions.
- Distinguish between a physical or chemical change.
- Distinguish among hypothesis, theory and law.
- Knowing the meaning of the prefixes used in the metric system, convert in one metric unit to another.
- Knowing that 2.54 cm = 1 in., 1.06 quarts = 1 liter, and 1 lb = 454 grams, convert between English and Metric units.
- Interconvert degrees Fahrenheit, Celsius and Kelvin.
- Using the density formula, solve for density, mass or volume, given the other two.
- Differentiate between exact numbers and measurements.
- Define and distinguish between precision and accuracy.
- Determine the correct number of significant figures in a measured or calculated quantity.
- Round off numbers to the correct number of significant figures.
- Express numbers and do calculations in exponential notation.
- Use dimensional analysis to solve unit conversion problems.
- Given the formula, name the elements and the binary compounds and vice versa (refer Nomenclature Handout: Sections I and II)
