Study Notes
Ecology
- The study of organisms and their relationship to the environment
- An organism's environment includes physical, chemical, and biological components
- Abiotic factors are non-living components of the environment
Abiotic Factors
- Temperature
- Sunlight
- Water
- Wind
- Pressure
- Soil/substrate
Temperature
- A physical property of matter that expresses hot and cold
- Measured with thermometers
- Common scales include Celsius (°C), Fahrenheit (°F), and Kelvin (K)
Temperature Conversions
- Fahrenheit to Celsius: °C = (°F - 32) × 5/9
- Celsius to Fahrenheit: °F = (°C × 9/5) + 32
- Celsius to Kelvin: K = °C + 273.15
- Kelvin to Celsius: °C = K - 273.15
Examples
- 26°C is equal to 78.8°F
- 98.6°F is equal to 37°C
- 27°C is equal to 300K
Temperature Measurement Instruments
- Liquid thermometers
- Sealed glass tube containing liquid (e.g., mercury or alcohol)
- The liquid expands and contracts with temperature changes
- Mercury-in-glass thermometer is a common type
- Alcohol thermometer is another common type
