The van der Waals constant for gases A , B , and C are as follows Answer the following: Which gas has the highest critical temperature?
Among noble gases,gas of highest density is He Kr Xe Rn
The rms velocity of a gas at T °C is double the value at 27 °C. The temperature T of the gas in °C is ( assume that the pressure remains constant)
Figure illustrates a cycle conducted with n moles of an ideal gas. In the states a and b the gas temperatures are T_(a) and T_(b) respectively. Temperature of the gas in the state C is ltbr)
Which gas will be adsorbed on a solid to greater extent? A) A gas having non-polar molecule B) A gas having highest critical temperature C) A gas having lowest critical temperature D) A gas having highest critical pressure .
One mole of a gas is in state A[P, V, T_(A)] . A small adiabatic process causes the state of the gas to change to B [P + dP, V + dV, T_(B)] . The changes dV & dP are infinitesimally small and dV is negative. An alternative process takes the gas from state A to B via A rarr C rarr B . A rarr C is isochoric and C rarr B is isobaric path. State at C is [P + dP, V, T_(C)] . (a) Rank the temperatures T_(A), T_(B) and T_(C) from highest to lowest. (b) Find g of the gas in terms of T_(A) , T_(B) and T_(C) .
