When we take the temperature of something, we are measuring its thermal energy, specifically its internal energy related to the motion of its particles. Temperature is a measure of the average kinetic energy of the particles in a substance. In simpler terms, it indicates how hot or cold an object is, which correlates with the speed at which its particles are moving; faster-moving particles result in a higher temperature, while slower-moving particles indicate a lower temperature. This measurement is typically expressed in units such as degrees Celsius (°C), degrees Fahrenheit (°F), or Kelvin (K).
