When a bottle of perfume is opened at one corner of a room, the entire room gets fragrant affter sometime-explain.

When a bottle of perfume is placed at one corner of room and the lid is opened , the scent spreads all over the room after sometimes . This happens by the process of

When a bottle of scent or ammonia is opened in one corner of a room, it can be smelled at the farthest corner after sometime due to the process of diffusion . At this stage , an equilibrium is reached due to the same concentration in space . At this point .

When a bottle of perfume is opened, odorus molecules mix with air and diffuse gradually throughout the room. The correct facts about the process are-

During summer if all the doors and windows are kept open and wet curtains are hung, the room remains moderately cool. Explain.

White fumes appear when bottles containing anhydrous AlCl_3 is opened for a fraction of time. Explain.

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement - I : When hydrogen gas expands adiabatically from high pressure to low pressure at room temperature then heating effect is observed. Statement - II: Hydrogen gas at room temperature is above its inversion temperature.

At room temperature 2NO+O_(2) to 2NO_(2) to N_(2)O_(4) reaction proceeds near to completion. The dimer, N_(2)O_(4) , solidified at 262K. A 250 mL flask and a 100 mL flask are separated by a stop-cock. At 300K, nitric oxide in the longer flask exerts a presure of 1.053 atm and and the smaller one contains oxygen at 0789 atm. the gases are mixed by opening the stopcock and after the end off the reaction the flasks are cooled to 220K. Neglecting vapour pressure of the dimer, find out pressure and composition of the gas remaining at 220 K (assume that the gases behave ideally).

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement - I: The pressure inside the LPG cylinder remains constant even when it is in use at room temperature. Statement - II : Vapour pressure of any liquid is independent of its amount, it depends only on temperature
