My school its Kelvin Temperature
The Kelvin temperature scale is the scale that is based on molecular motion and so absolute zero is also called 0 K. The Kelvin temperature of a substance is directly proportional to the average kinetic energy of the particles of the substance
The relationship between the average kinetic energy of gas molecules and temperature is expressed in terms of Kelvin (K), not Celsius (°C). In the kinetic theory of gases, temperature is measured on the Kelvin scale, where 0 K represents absolute zero (the lowest possible temperature).
The equation relating average kinetic energy (\(KE\)) and temperature (\(T\)) is:
\[ KE = \frac{3}{2} k \cdot T \]
where:
- \( KE \) is the average kinetic energy of a gas molecule,
- \( T \) is the temperature of the gas in Kelvin,
- \( k \) is the Boltzmann constant (\( k \approx 1.38 \times 10^{-23} \, \text{J/K} \)).
It's important to convert temperatures to Kelvin when using this equation in calculations related to the kinetic theory of gases. The Kelvin scale is derived from the Celsius scale by adding 273.15, so \(0 \, \text{°C}\) is equivalent to \(273.15 \, \text{K}\).
The average kinetic energy of the molecules of a perfect gas is directly proportional to the absolute temperature, which is the kelvin temperature. However, the supposed correct answer here is Celsius temperature.
