這篇文章是關於溫度、溫度計、校準以及熱容量的介紹。它首先解釋了溫度的定義,並列出了不同類型的溫度計,包括紅外線溫度計、電阻溫度計和玻璃中的汞溫度計。接著詳細說明了溫度計的校準步驟,包括冰點校準和沸點校準。最後講解了熱容量的概念,包括熱容量(C)和比熱容量(c)的定義及計算公式。文章內容清晰,適合學習溫度和熱物理相關知識的人閱讀。
# Definition of Temperature
Temperature is a measure of degree of hotness of an object. (Oxford TB 2nd edition, 2014)
# Thermometer
# Type of Thermometers
- Infrared thermometer
- Resistance thermometer
- Mercury-in-glass thermometer
# Thermometer Calibration
Thermometer calibration ensures accurate temperature measurement. It involves adjusting a thermometer to match a known standard.
# Steps for Calibration:
-
Ice Point Calibration (0°C)
- Place the thermometer in a mixture of crushed ice and water.
- Wait for it to stabilize, then adjust if needed to read 0°C.
-
Boiling Point Calibration (100°C)
- Place the thermometer in boiling water (at sea level).
- Ensure it reads 100°C; adjust if necessary.
-
Using a Reference Thermometer
- Compare readings with a calibrated standard thermometer at different temperatures.
-
Adjust and Record
- If there is a deviation, apply a correction factor.
- Document the calibration results for future reference.
# Heat Capacity
# Heat Capacity (C)
where
- = Heat Energy (Unit: )
- = Heat Capacity (Unit: / )
# Specific Heat Capacity (c)
where
- = Heat Energy (Unit: )
- = Specific Heat Capacity (Unit: / )
The letter 'c' in specific heat capacity MUST ALWAYS BE LOWERCASE!
- = mass of an object (unit: kg)
- = change in temperature (unit: °C)
