Property of Substance
- Combine solid A and solid B with a red liquid in a paper bag to make a reaction.
- Reaction - Warm and cold, yellow, bubbly, bag inflates, solids dissolve, and a gas filled up the bag.
- When baking soda is heated it turns into a different substance.
- Heated baking soda in tea is a different color than non-heated baking soda in tea.
- Condensation formed near the top of the test tube.
1.2 Notes: Volume
- L x W x H
- Standard unit of length = Meter (m)
- 100 centimeters = 1 m
- Use a graduated cylinder to measure volume
- 1 mL = 1 cm^3
1.4 Lab: Measuring Volume by Displacement of Water
- (Sand + Water) - Water = Sand alone
- (Dry sand + Air) - Sand alone = Volume of air
- % of sand that is air = is/of = air/dry sand
1.8 Lab: The Sensitivity of a Balance
- 0.02 is the sensitivity of our balances.
- When adding salt into water, the mass decreases.
2.4 Lab: The Mass of Ice and Water
- Condensation easily forms
2.5 Lab: The Mass of Copper and Sulfur
- Condensation, white-yellow gas, bubbles, black liquid that turned clear, and a new black solid after the reaction.
2.6 Lab: Mass of a Gas
- There should be no change in mass.
- Objects made of the same substance and have the same volume, will have the same mass.
- Objects made of different substances, but have the same volume, will not have the same mass.
3.5 Lab: The Density of Solids
3.6 Lab: The Density of Liquids
3.7 Lab: The Density of a Gas
