The graph, shown in the adjacent diagram, represents the variation of ...

The graph sh ows that for the same temperature difference (T₂ – T₁), less time is taken for x. This means the emissivity is more for x. According to Kirchoff's law, a good emitter is a good absorber as well.

In the Figure, isotherms of CO2 at several temperatures near the critical point are shown. At the critical point (critical stat e), the distinction between the liquid and gaseous states disappear and the density of the gaseous substance is equal to that in the liquid state. For every gas this occurs at specific values of temperature and pressure, called critical temperature and critical pressure respectively. At temperatures and pressures above the critical point value, a gas is said be in a supercritical state. Critical constants are evaluated by solving the Vander W aals equation which is a cubic involume. The values are TcIn the supercritical region the behaviour is studied by plotting Z vs P plots. The variation in this region is studied with respect to boyles temperature aAt temperaturehigher than CB the variation is linear (Plot I) and at temperature lower than CB the variation is non linear (Plot II) With reference to the passage answers the following questions:Q.Two Vander waals gases have same value b but different a value then which of the following statement is correct under similar condition.
