What does “Internal energy” actually mean in Thermodynamics & Kinetic Theory, and why does it matter for NEET?
the total microscopic energy of a system; for an ideal gas it depends only on temperature.
In simple words: the total microscopic energy of a system; for an ideal gas it depends only on temperature. Getting Internal energy clear matters because NEET questions on Thermodynamics & Kinetic Theory usually test this idea directly, not just a formula you memorised.
Key point
Internal energy
Common mistake
thinking internal energy depends on pressure or volume for an ideal gas.
Memory tip
same temperature → same internal energy for an ideal gas.
