Study Notes
Heat and Temperature
- Heat is the total energy of molecular motion in a substance.
- Temperature is a measure of the average kinetic energy of the molecules in a substance.
- Heat is a form of energy that can be transferred, while temperature is a measure of the intensity of that energy.
Modes of Heat Transfer
- Conduction: Heat transfer through direct contact between molecules.
- Convection: Heat transfer through the movement of fluids (liquids or gases).
- Radiation: Heat transfer through electromagnetic waves.
Clinical vs. Laboratory Thermometers
- Clinical thermometers: Used to measure body temperature, typically accurate to within 0.1 degrees Celsius.
- Laboratory thermometers: Used for scientific measurements, designed for greater accuracy with finer graduations and wider temperature ranges.
Temperature Conversions
- Celsius to Fahrenheit: F = (C * 9/5) + 32
- Fahrenheit to Celsius: C = (F - 32) * 5/9
- Celsius to Kelvin: K = C + 273.15
- Kelvin to Celsius: C = K - 273.15
- Fahrenheit to Kelvin: K = (F - 32) * 5/9 + 273.15
- Kelvin to Fahrenheit: F = (K - 273.15) * 9/5 + 32
Conversions
- 100 degrees Celsius is equal to 212 degrees Fahrenheit.
- 50 degrees Fahrenheit is equal to 10 degrees Celsius.
- 300 Kelvin is equal to 27 degrees Celsius.
- 200 Kelvin is equal to -93.33 degrees Fahrenheit.
- 100 degrees Fahrenheit is equal to 310.93 Kelvin.
- 500 Kelvin is equal to 226.85 degrees Celsius.
