Temperature and Measurement – Explanation with Example
Temperature and Measurement
Key Concepts
- Temperature
- Scales in which temperature is measured
- 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:
- Celsius scale
- Fahrenheit scale
- Kelvin scale
Important scales to remember:
- Celsius scale is measured from the value 0 °c to 100 °c.
- Fahrenheit is measured from the value 32 °F to 212 °F.
- 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:
