314063 Statement A :
At constant temperature, \(\mathrm{p V}\) versus \(\mathrm{p}\) plot for ideal gas is a straight line.
Statement B :
At high pressure all gases have \(\mathrm{Z < 1}\) but at intermediate pressure most gases have \(\mathrm{Z>1}\).

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.

1 \({\mathrm{Z=\dfrac{V_{\text {ideal }}}{V_{\text {real }}}}}\)
2 \({\mathrm{p_{\text {ideal }}=p_{\text {real }}+\dfrac{a n^{2}}{\mathrm{~V}^{2}}}}\)

314047 The temperature at which real gases obey the ideal gas laws over a wide range of pressure is called

1 critical temperature
2 inversion temperature
3 Boyles temperature
4 reduced temperature
CHXI06:STATES OF MATTER

314048 A gas is said to behave like an ideal gas when the relation \(\mathrm{\mathrm{PV} / \mathrm{T}=}\) constant. When do you expect a real gas to behave like an ideal gas?

1 when the temperature is low
2 when both the temperature and pressure is low
3 when both the temperature and pressure are high
4 when the temperature is high and pressure is low
