How Kinetic Theory of Gases Can Shape Your JEE Main 2025 Journey?

Kinetic Theory of Gases are like the backbone of physics, and they play a pivotal role in JEE Main Important Questions. By mastering this chapter, you grasp the fundamental concepts of molecular motion, kinetic energy, and gas behavior, enabling a deeper understanding of gases' physical properties and behavior. Here, we'll delve into why acing this chapter is essential for excelling in JEE Main and conquering those high-scoring questions.


Gas Molecules in Motion:

  • Imagine a bustling crowd – that's how gas molecules are in constant motion!

  • The Kinetic Theory of Gases unveils this dance of particles, explaining how they zoom around at different speeds.


Temperature's Play:

  • Temperature isn't just a number – it's the energy of gas molecules' motion.

  • The hotter it is, the more energetic the dance becomes. Cooler? They slow down.


Tiny but Powerful:

  • Gas molecules are teeny-tiny, but they pack a punch!

  • Their collisions create pressure – that's what pushes tires and inflates balloons.


Elastic Collisions:

  • When gas molecules collide, they're like bouncy balls.

  • They don't lose energy – it's conserved. So they bounce off, changing speed and direction.


Ideal vs. Real:

  • Ever heard of "ideal" gases? They follow Kinetic Theory to the letter.

  • Real gases get cozy and stick together sometimes. Kinetic Theory explains why they might not be "ideal" pals.


Mean Free Path:

  • Imagine a busy street – gas molecules "walk" in zigzags.

  • The distance they travel before bumping into others is the "mean free path." Busy streets mean shorter paths!


Brownian Motion:

  • Even in still air, pollen dances. Thanks to gas molecules!

  • This "Brownian motion" is like a microscopic disco – tiny pollen particles jitter around.


Absolute Zero:

  • Imagine the coldest chill – that's absolute zero, where molecules stand still.

  • You can't reach it, but the Kinetic Theory gives us a sneak peek into the coldest dance floor.


Practical Magic:

  • Kinetic Theory isn't just for the lab – it's everyday magic!

  • From understanding air pressure to why a balloon inflates, it's like seeing the world with scientific glasses.


Beyond the Classroom:

  • Kinetic Theory isn't just about exams – it's about understanding the air we breathe and the gases that fill our world.

  • So, put on your scientific explorer's hat and dive into the mesmerizing world of Kinetic Theory!

$\mathrm{k}_{\mathrm{B}}$ is the Boltzmann's constant

$\mathrm{R}$ is the gas constant

$\mathrm{n}$ is the number of moles

$\mathrm{N}$ is the number of particles in one mole (the Avogadro number)


2. Total Translational K.E of Gas

$K . E=(3 / 2) n R T$

$\mathrm{n}$ is the number of moles

$\mathrm{R}$ is the universal gas constant

$V_{r m s}>V>V_p$

$V_{\text {rms }}$ is the RMS speed

$V$ is the Average speed

$V_p$ is the most probable speed


4. RMS Speed $(\left.\mathrm{V}_{\mathrm{rms}}\right)$

$V_{r m s}=\sqrt{\frac{3 k t}{m}}=\sqrt{\frac{3 R T}{M}}$

$\mathrm{R}$ is the universal gas constant $\mathrm{T}$ is the absolute temperature $\mathrm{M}$ is the molar mass


5. Average Speed (v)

$\vec{v}=\sqrt{\frac{8 k t}{\pi m}}=\sqrt{\frac{8 R T}{\pi M}}$


6. Most Probable Speed $\left(v_p\right)$

$v_p=\sqrt{\frac{2 k t}{m}}=\sqrt{\frac{2 R T}{M}}$


7. Pressure of Ideal Gas

$\mathrm{p}=1 / 3 \rho \mathrm{v}_{\mathrm{rms}}^2$

$\rho$ is the density of molecules


8. Equipartition of Energy

$K=1 / 2 k_B T$ for each degree of freedom

$K=(f / 2) k_B T$ for molecules having $f$ degrees of freedom

$\mathrm{k}_{\mathrm{B}}$ is the Boltzmann's constant

$\mathrm{T}$ is the temperature of the gas


9. Internal Energy
