Study Notes
Properties of Water and Its Containers
- Closed water bottle: Maintains temperature due to reduced evaporation; ideal for transporting liquids while minimizing contamination.
- Open water bottle: Facilitates easy access to water but allows for evaporation and potential contamination.
- Thermos flask: Designed to insulate and maintain the temperature of liquids; utilizes vacuum insulation to minimize heat transfer.
Temperature Measurement
- Medical thermometer: Used to measure body temperature; essential for diagnosing fever or hypothermia. Often calibrated in Celsius or Fahrenheit.
Cooling and Refrigeration
- Refrigerator: Essential for preserving food and beverages by slowing bacterial growth; operates using a refrigeration cycle involving refrigerants.
Cooking and Pressure Management
- Pressure cooker: Cooks food faster by increasing pressure and raising boiling point of water; can achieve cooking temperatures above normal boiling point of 100°C.
Water Bodies and Storage
- Pool filled with water: Offers recreational opportunities; often treated with chemicals to maintain water quality and prevent algae growth.
- Beaker filled with water: Common laboratory equipment for measuring and mixing liquids; its wide mouth allows for easy pouring and stirring.
Chemical Storage
- Benzene tank: Used for storing benzene, an organic chemical; must be managed carefully due to its toxic and flammable properties.
