2. The SI unit of temperature is the kelvin (K). However, the degree Celsius (°C) is more commonly used.
3. A thermometric property is a physical property that changes according to temperature. To define a temperature scale, a thermometric property that varies linearly with temperature is used.
4. In the Celsius scale, two fixed points are used: ice point and steam point. They are 0°C and 100°C respectively. Each interval on the thermometer measures 1°C.
5. A thermometer is a device used to measure the temperature of an object.
