# Joint Entrance Examination/AIEEE 2009/Q073 physiosorption

* Welcome to the Highschool Help Forum!
* The forum is currently in "Beta" stage of development. You can ask questions and answer/discuss them. The basic functionalities are present. What's required is a more aesthetic look to the Static pages and a more user friendly setup. This will happen over the time gradually as we start creating some content.
* The site has a lot of tools, like posting mathematical calculations, images and diagrams; categorizing questions and so on. Having them here is NO GOOD unless you know how to use them. I am thoroughly against compiling a list of these features and then writing about them. As soon as you do not understand how to do something or use a certain feature, report that on "How To"s Section of the forum. Your queries will be answered there.
* If you have any ideas/discussion regarding the site/comments, please go to Discussions regarding Highschool Help Forum
* Lastly, thanks for joining in the site's development process! It matters!

| Original Question by 164.100.170.4 Here's the question... Which of the following statements is incorrect regarding physiosorption? *(1) Enthalpy of adsorption (Hadsorption) is low and positive. *(2) It occurs because of Van der Waal’s forces. *(3) More easily liquefiable gases are adsorbed readily. *(4) Under high pressure it results into multi molecular layer on adsorbent surface.

Additional notes
H for adsorption is negative. Adsorption is a spontaneous process, so G is negative and S in case of adsorption is also
negative.  G = H – TS. Therefore, H is –ve.
