‘n’ moles of an ideal gas undergoes a process A→ B as shown in the figure. The maximum temperature of the gas during the process will be

When volume of system is increased two times and temperature is decreased half of its initial temperature, then pressure becomes

Two thermally insulated vessels 1 and 2 are filled with air at temperatures (T1,T2) volume (V1,V2) and pressure (P1,P2) respectively. If the valve joining the two vessels is opened, the temperature inside the vessel at equilibrium will be

An ideal gas is initially at temperature T and volume V. Its volume is increased by ΔV due to an increase in temperature ΔΤ, pressure remaining constant. The quantity δ = ΔV/(VΔT) varies with temperature as

Match Column-1 and Column-II and choose the correct

Kinetic theory of gases provides a base for

For a gas at a temperature T the root-mean-square velocity υ rms, the most probable speed υmp, and the average speed υav obey the relationship

When an ideal monoatomic gas is heated at constant pressure, fraction of heat energy supplied which increases the internal energy of gas, is

The figure below shows the plot of PV/ nT versus P for oxygen gas at two different temperatures

If pressure of CO₂ (real gas) in a container is given by P= (RT/ 2V-b) – (a/ 4b^2), then mass of the gas in container is2
