314065 Identify the wrong relation for real gases :

1 \({\mathrm{Z=\dfrac{V_{\text {ideal }}}{V_{\text {real }}}}}\)
2 \({\mathrm{p_{\text {ideal }}=p_{\text {real }}+\dfrac{a n^{2}}{\mathrm{~V}^{2}}}}\)
3 \({\mathrm{\mathrm{V}_{\text {real }}=\mathrm{V}_{\text {ideal }}-\mathrm{nb}}}\)
4 \({\mathrm{\left(p+\dfrac{a}{V^{2}}\right)(V-b)=R T}}\)

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
