Question

directions: using the lesson notes for the topics below, fill in the study guide below to help you prepare for the semester 1 final exam on friday, december 12th. the bullet points that have bolded text are concepts, terms, or processes that you need to know for the final exam. how to fill in study guide: - if it is a vocabulary term, write the definition next to the term. - if it is a calculation, solve the sample calculation and (optional) provide the steps on how to solve those types of problems. - if it is an identification, write the keywords that will help you identify it easily. unit 1 material: - define: - matter = - mass = - volume = - density = - water displacement method =

Explanation:

The problem involves defining scientific terms related to matter (like Matter, Mass, Volume, Density, Water displacement method) which falls under the Natural Science discipline, specifically Chemistry (as it's a Chemistry study guide) or Physics (since these are basic physical properties of matter). The task is to provide definitions for these vocabulary terms. For example:

• Matter: Anything that has mass and occupies volume (has space). Keywords: mass, volume, substance.
• Mass: A measure of the amount of matter in an object. Unit: gram (g), kilogram (kg). It's a scalar quantity, constant regardless of location.
• Volume: The amount of space occupied by a substance. For solids: \( V = l \times w \times h \) (for regular shapes); for liquids: measured with graduated cylinder; for irregular solids: water displacement method. Unit: cubic meter (\( m^3 \)), liter (L), milliliter (mL).
• Density: The mass per unit volume of a substance. Formula: \(

ho = \frac{m}{V} \), where \(
ho \) is density, \( m \) is mass, \( V \) is volume. Unit: \( \frac{g}{cm^3} \) or \( \frac{kg}{m^3} \). It helps identify substances (each has unique density).

• Water displacement method: A technique to find the volume of an irregularly - shaped solid. Steps: 1. Fill a graduated cylinder with water and record the initial volume (\( V_1 \)). 2. Submerge the solid completely in the water (without splashing). 3. Record the new volume (\( V_2 \)). 4. Volume of the solid \( V = V_2 - V_1 \).

Answer:

• Matter: Anything with mass and volume.
• Mass: Amount of matter in an object.
• Volume: Space occupied by a substance.
• Density: \(

ho=\frac{m}{V} \) (mass per unit volume).

• Water displacement method: Finds volume of irregular solids (\( V = V_2 - V_1 \)).
