An ideal gas undergoes isobaric expansion at pressure P from volume V_1 to V_2 the work done is :

For an ideal gas V - T curves at constant pressure P_(1) & P_(2) are shown in figure, from the figure

Which one of the following relationships when graphed does not give a straight line for helium gas? I. K.E. and T at constant pressure and volume II. P v/s V at constant temperature for a constant mass III. V v/s 1/T at constant pressure for a constant mass

An ideal gas with pressure P, volume V and temperature T is expanded isothermally to a volume 2V and a final pressure P_i , If the same gas is expanded adiabatically to a volume 2V and a final pressure P_alpha find the value of ratio P_alpha/P_i . The ratio of the specific heats for the gas is 1.67.

What is the nature of graph between pressure P and volume V for a gas at constant temperature?

Two cylinders A and B of equal capacity are connected to each other via a stopcock. A contains a gas at standard temperature and pressure. B is completely evacuated. The entire system is thermally insulated. The stopcock is suddenly opened. Answer the following : Do the intermediate states of the system (before settling to the final equilibrium state) lie on its P-V-T surface ?

The graph of compressibility factor (Z) vs. P for one mole of a real gas is shown in following diagram. The graph is plotted at constant temperature 273K. If the slope of graph at very high pressure ((dZ)/(dP)) is ((1)/(2.8))atm^(-1) , then calculate volume of one mole of real gas molecules (in L/mol) Given : N_(A)=6xx10^(23) and R=(22.4)/(273)L atmK^(-1)mol^(-1)

A gas expands against a variable pressure given by P = (20)/(V) (where P in atm and V in L). During expansion from volume of 1 litre to 10 litre, the gas undergoes a change in internal energy of 400 J. How much heat is absorbed by the gas during expansion?
