What Is Temperature?
Temperature is a measure of how hot or cold an object, substance, or environment is, typically expressed in degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K). In the context of weather, it reflects the level of heat energy in the atmosphere at a given time and location. Temperature plays a key role in determining the overall weather conditions, including wind, precipitation, and humidity levels.
The concept of temperature is rooted in the kinetic theory of matter, which states that the molecules in a substance are in constant motion. When these molecules move faster, the temperature increases; when they move slower, the temperature decreases. This fundamental principle applies to everything from boiling water to the air we breathe.
In weather forecasts, temperature is one of the most important variables, often serving as a starting point for understanding broader climatic patterns. Whether you’re planning a picnic, going for a jog, or simply stepping out for errands, knowing the temperature helps you dress appropriately and stay prepared.
