Meaning of temperature
Temperature is the degree of hotness or coolness of a body. Hotter the body higher is its temperature. The temperature will determine the direction of heat flow when two bodies are in thermal contact.
The SI unit of temperature is kelvin (K).
In our day to day applications, Celsius (˚C) and Fahrenheit (°F) scales are used.
Temperature is measured with a thermometer.
The conversion of temperature from one scale to other scale is given in Table 8.1
