Welcome!
Hello and welcome to Wikipedia. We appreciate encyclopedic contributions, but some of your recent contributions, such as your edit to the page Mass transfer, seem to be advertising or for promotional purposes. Wikipedia does not allow advertising. For more information on this, please see: If you still have questions, there is a new contributors' help page, or you can. You may also find the following pages useful for a general introduction to Wikipedia: I hope you enjoy editing Wikipedia!

Please stop adding inappropriate external links to Wikipedia, as you did to Vapor pressure. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you may be blocked from editing Wikipedia. - Arjayay (talk) 11:40, 9 April 2019 (UTC)

You may be blocked from editing without further warning the next time you insert a spam link, as you did at Vapor pressure. Persistent spammers may have their websites blacklisted, preventing anyone from linking to them from all Wikimedia sites as well as potentially being penalized by search engines. - Arjayay (talk) 11:43, 9 April 2019 (UTC)
