Question

The average kinetic energy of gas molecules is ________ proportional to the absolute temperature.

Answer 1

The average Kinetic energy of the molecules of a gas is directly proportional to the absolute temperature.

How is K.E proportional to absolute temperature?

We know that Kinetic energy is given by the equation ,

$K = \frac{1}{2} mv^{2}$

where ,

K = kinetic energy

m = mass

v = velocity

1. Since the square of a particle's velocity is precisely proportional to the kinetic energy of a gas, kinetic energy likewise rises when temperature rises.
2. As a result, the relationship between a gas's kinetic energy and absolute temperature is linear.
3. The kinetic energy of the gas molecules increases as the temperature rises, increasing their rate of motion.
4. The speed of the gas molecules' motion, or their kinetic energy, falls as the temperature drops.
5. A gas's average molecular kinetic energy is inversely related to its absolute temperature.

What is absolute temperature?

The Kelvin scale, where 0 represents absolute zero, is used to measure absolute temperature. The temperature at which matter's particles move the least and cannot cool down is known as the zero point (minimum energy). A thermodynamic temperature reading does not include a degree symbol because it is "absolute" in nature.
