Physics Thermodynamics questions from NEET UG 2023.
A Carnot engine has an efficiency of $50%$ when its source is at a temperature $327^{\circ}C.$ The temperature of the sink is:
A container of volume $200 \mathrm{~cm}^3$ contains 0.2 mole of hydrogen gas and 0.3 mole of argon gas. The pressure of the system at temperature $200 \mathrm{~K}\left(R=8.3 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}\right)$ will be
For the given cycle, the work done during isobaric process is: 
The temperature of a gas is $-50^{\circ}C$. To what temperature the gas should be heated so that the rms speed is increased by $3$ times?
