# 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

### 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
1. Fahrenheit scale
1. Kelvin scale

### Important scales to remember:

1. Celsius scale is measured from the value 0 °c to 100 °c.
1. Fahrenheit is measured from the value 32 °F to 212 °F.
1. 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:

#### Define Position Time Graph and its Types

Key Concepts • Slope of a graph • Position time graph • Slope of s-t graph = Velocity • Types of position time graphs Introduction An object in a uniform motion covers equal distances in equal intervals of time. This also indicates that it moves at a constant velocity. When its position at different instants […]

#### Magnetic Field Lines: Definition, Explanation and Q&A

Key Concepts Magnetic Field Magnetic Field Lines properties of magnetic field lines Uniform and non uniform magnetic lines Introduction Two magnets when placed close to each other attract and stick to each other. However, if we go on increasing the distance between them, the attraction between them reduces gradually to such an extent that they […]

#### The Life Cycles of Stars: Meaning and Example

Key Concepts Stars Analysis of starlight Composition of stars Stars’ temperature Size and mass of stars Stages of life cycle of a star Introduction Stars are huge, shining balls of extremely hot gas (known as plasma) in space. The Sun is our nearest star. During the nighttime, many other stars are visible to the naked […]
