Seema visited a Natural Gas Compressing Unit and found that the gas can be liquefied under specific conditions of temperature and pressure. While sharing her experience with friends she got confused. Help her to identify the correct set of conditions. (a) Low temperature, low pressure (b) High temperature, low pressure (c) Low temperature, high pressure (d) High temperature, high pressure
(c) Low temperature, high pressure Gases can be liquefied by lowering the temperature and increasing the pressure. Low temperature slows down gas molecules, reducing their kinetic energy, while high pressure forces the molecules closer together, allowing them to form a liquid state. https://www.tiwaRead more

A black body at 20 K is found to emit maximum energy at a wavelength 14 µm. When its temperature is raised to 1000K, then wavelength at which maximum energy emitted is
According to Wien's displacement law, the wavelength at which the black body emits maximum energy varies inversely with temperature: λ_max * T = constant Let the initial temperature be 20 K with a wavelength of 14 µm, and the final temperature be 1000 K. Given that using Wien's law, λ₁ * T₁ = λ₂ * TRead more
According to Wien’s displacement law, the wavelength at which the black body emits maximum energy varies inversely with temperature:
λ_max * T = constant
Let the initial temperature be 20 K with a wavelength of 14 µm, and the final temperature be 1000 K. Given that using Wien’s law,
λ₁ * T₁ = λ₂ * T₂
14 µm * 20 K = λ₂ * 1000 K
λ₂ = (14 µm * 20 K) / 1000 K
λ₂ = 280 µm / 1000
λ₂ = 0.28 µm
Thus, the correct answer is: 2.8 µm
