Questions
A cylinder containing an ideal gas is in vertical position and has a piston of mass M that is able to move up or down without friction (see figure). If the temperature is increased, then [NCERT Exemplar)
detailed solution
Correct option is C
Consider the diagram, where an ideal gas is contained in a cylinder, having a piston of mass M. Friction is absent.The pressure inside the gas will be p = pa + Mg/Awhere, pa = atmospheric pressure, A = area of cross-section of the pistonand Mg = weight of piston.Hence, p = constantAs, pV = nRT⇒When temperature increases, volume (V) increases at constant pressure.Similar Questions
For one-mole ideal gas, a process follows the relation where P0 and V0 are constants. If the volume the gas changes from V0 to 2V0. What is the change in temperature?
