Temperature is a measure of how hot or cold something is. It tells us about the energy of the particles in an object. When particles move quickly, the temperature is high, and when they move slowly, the temperature is low. We often use tools like thermometers to measure temperature in degrees Celsius or Fahrenheit. Understanding temperature is important in our daily lives. For example, it helps us decide what to wear, like a warm coat in cold weather or light clothing in summer. It also plays a crucial role in cooking, as different recipes require specific temperatures to ensure food is safe and delicious.
