Select incorrect statements for real gas:a)In low pressure region repu...
**Explanation:**
When considering real gases, the following statements are incorrect:
**a) In the low pressure region, repulsive forces dominate, and in the high pressure region, attractive forces dominate.**
This statement is incorrect because in the low pressure region, the intermolecular forces are weak, allowing the gas particles to move freely and behave more like an ideal gas. In the high pressure region, the gas particles are closer together, and the attractive forces between the particles become significant. Therefore, attractive forces dominate in the low pressure region, and repulsive forces dominate in the high pressure region.
**b) Volume of gas particles is not negligible in the low-pressure region.**
This statement is incorrect because at low pressure, the volume of the gas particles becomes significant compared to the total volume of the gas. The individual gas particles occupy a certain amount of space, and this volume cannot be ignored when considering the behavior of a real gas. In an ideal gas, the volume of the gas particles is assumed to be negligible compared to the total volume of the gas.
**c) Gases behave as an ideal gas at low pressure and low temperature.**
This statement is incorrect because at low pressure and low temperature, the behavior of gases deviates from that of an ideal gas. At low pressure, the gas particles are closer together, and the intermolecular forces become significant, causing deviations from ideal gas behavior. At low temperature, the kinetic energy of the gas particles decreases, and they move more slowly, which also leads to deviations from ideal gas behavior.
Therefore, all the given statements are incorrect, and the correct answer is option 'D' - All of the above.
