$$0.5$$ moles of an ideal gas at constant temperature $$27^{\circ}C$$ kept inside a cylinder of length $$L$$ and cross-section area $$A$$ closed by a massless piston.
The cylinder is attached with a conducting rod of length $$L$$, cross-section area $$(\dfrac{1}{9})m^{2}$$ and thermal conductivity $$k$$, whose other end is maintained at $$0^{\circ}C$$. If piston is moved such that rate of heat flow through the conducing rod is constant then velocity of piston when it is at height $$\dfrac{L}{2}$$ from the bottom of cylinder is:
[Neglect any kind of heat loss from system]

The difference between volume and pressure coefficients of an ideal gas is :

A sealed glass jar is full of water. When it is kept in a freezing mixture, it is broken because :

The gas law $$\left [ \dfrac{PV}{T} \right ]=$$ constant is true for

b.$$\gamma _{r}$$of water is - ve                    f. 277 K

c. $$\gamma _{r}$$ of water is positive            g. above 277 K

Water at $$4^{0}$$C is filled to the brim of 2 beakers. A boy performed an experiment A of heating and B of cooling. The observation was :

The P-T graph for the given mass of an ideal gas is shown in figure. Then the volume

A gas in an airtight container is heated from 25$$^{o}$$C to 90$$^{o}$$C. The density of gas will :

A sealed glass jar is full of water. When its temperature is decreased to $$0^{o}C$$ :

The molar gas constant is the same for all gases because at the same temperature and pressure, equal volumes of gases have the same :
