Temperature

Temperature is a measure of how hot or cold something is. It is a fundamental concept in science and is used in various everyday applications. The standard unit of temperature is the degree Celsius (°C), but the Fahrenheit (°F) and Kelvin (K) scales are also commonly used.

Scales of Temperature

1. Celsius (°C): The Celsius scale is based on the freezing point of water at 0°C and the boiling point of water at 100°C under standard atmospheric pressure.

2. Fahrenheit (°F): The Fahrenheit scale is based on the freezing point of water at 32°F and the boiling point of water at 212°F under standard atmospheric pressure.

3. Kelvin (K): The Kelvin scale is based on absolute zero, the point at which all molecular motion ceases. The freezing point of water is 273.15 K, and the boiling point of water is 373.15 K.

Converting Between Scales

To convert temperatures between Celsius, Fahrenheit, and Kelvin, you can use the following conversion formulas:

Celsius to Fahrenheit: °F = (°C × 9/5) + 32

Fahrenheit to Celsius: °C = (°F - 32) × 5/9

Celsius to Kelvin: K = °C + 273.15

Kelvin to Celsius: °C = K - 273.15

Fahrenheit to Kelvin: K = (°F - 32) × 5/9 + 273.15

Kelvin to Fahrenheit: °F = (K - 273.15) × 9/5 + 32
