ICSE Physics class 6, Temperature

🌈 Temperature

🔴 Definition
Temperature is the degree of hotness or coldness of a body.

🟠 SI Unit
kelvin (K) is the SI unit of temperature.

🟡 Temperature Scales
Celsius, Fahrenheit and Kelvin scales.

🟢 Measuring Device
Temperature is measured using thermometer.
