RRB JE 2014 30 questions part 5 The pressure exerted on the walls of container by a gas is due to the fact that Gas molecules: Srick to the walls of the container Lose their kinetic energy Get accelerated towards the wall Change their momentum due to collision with the wall. The thermal diffusivity of a substance is given by : Kp/C K/pC KC/p pC/K . Boyle’s ;aw states that : The pressure of a gas varies directly with temperature at constant volume i.e. Pat. The product of pressure and volume of a given mass of as gas is constant at constant temperature The volume of a gas varies directly with temperature at constant pressure i.e. VaT. The pressure of a gas varies directly with volum at constant temperature i.e. PaT. At what temperature, both Celsius and Fahrenheit scales will show the identical readings ? 100o 0o -40o 40o A capacitor stores 1 coulomb at 10 volts. It capacitance is (f = farad) : 1 f 10 f 0.1 f 0.01 f Who is the Chairperson of Nati...
