1.	Assertion: The pressure of a fixed amount of an ideal gas is proportional to its temperature. Reason: The Frequency of collisions and their impact both increase in proportion of the square root of temperature.A. If both (`A`) and (`R`) are correct and (`R`) is the correct explanation of (`A`).B. If both (`A`) and (`R`) are correct, but (`R`) is not the correct explanation of (`A`).C. If (`A`) is correct, but (`R`) is incorrect.D. If (`A`) is incorrect, but (`R`) is correct.
Answer» Assertion is true, reason is true, reason is not the correct explanation for assertion. The pressure of a fixed amount of an ideal gas is proportional to its temperature. `v_(rms) prop sqrt(T)` Collision frequency is directly proportional to `v_(rms)`. On increasing the collision frequency, the pressure increases.

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressyre and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas beheviour as compared to the gases which are liqufied with diffculty. Gas deviates from ideal gas beheviour because moleculesA. are coloulessB. attract each otherC. contain covalent bondD. show Brownian Movement.
