Questions
A horizontal narrow glass tube of 100 cm length closed at both ends contains a gas divided in to equal parts by a mercury pellet 10 cm long with the system at . Now one side is heated to , while the other side is cooled to . The distance moved by the mercury pellet in cm is nearly (neglect expansion of glass and mercury)
detailed solution
Correct option is A
Initially both sides contain same number of moles and finally also they must contain same number of moles. If x is displacement of mercury pellet on the hot side the length of gas column is (45 + x) and on the cold side it is (45 - x). The pressures on both sides are equal and apply PV = nTR for hot side and cold sideTalk to our academic expert!
