Mathematics · Thermodynamics and Kinetic Theory
A closed tube filled with an ideal gas is rotating with a constant angular velocity ω about one end A. If the pressure at end A is PA, then the pressure at the other end B of length ℓ is given by: (M is the molar mass of the gas, T is the absolute temperature, and R is the universal gas constant)
- 1PA eω2 ℓ2 M4RT
- 2PA eω2 ℓ2 M3RT
- 3PA eω2 ℓ2 MRT
- 4PA eω2 ℓ2 M2RT✓
Correct answer
PA eω2 ℓ2 M2RT
