Temperature and Measurement – Explanation with Example

Temperature and Measurement 

 Key Concepts

1. Temperature
2. Scales in which temperature is measured
3. Relation between the scales of temperature

Explanation

Temperature 

The degree of hotness or the coldness of a body is called temperature. Temperature is denoted by the letter ‘T’. 

Temperature is measured using the device thermometer. 

With the increase in the temperature, the kinetic energy in a body increases; hence we can say the temperature is proportional to the kinetic energy. 

Scales of temperature: 

Temperature can be measured on three scales: 

1. Celsius scale 

2. Fahrenheit scale 

3. Kelvin scale 

Important scales to remember: 

1. Celsius scale is measured from the value 0 °c to 100 °c. 

2. Fahrenheit is measured from the value 32 °F to 212 °F. 

3. Kelvin scale is measured from the value -373 K to +373 K. 

Relation between the scales of temperature 

Relation between Celsius and Fahrenheit scale: 

     (Where L.P = Lower point, H.P = Higher Point on the scale) 

Relation between Celsius and kelvin scale: 

K = C + 273 

Relation between kelvin and Fahrenheit scale:
