This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Android keeps closed applications on memory as long as possible so that when you return to the application it will still be on memory and will load faster than loading from the internal memory or SD card; but if another applications needs memory, unused applications and background applications will be automatically force killed to give way to the foreground activity.

In short, Android is not Windows, don't treat them the same.

You should only force close misbehaving applications, not for freeing memory; without a dedicated task killer, you can do this from Settings > Applications > Manage Applications > *name of application* > Force Stop

Does this consume more battery power ...... – prasonscala Dec 16 '10 at 10:48
@prassee: No, applications that simply sleeps in the background does not consume more battery or use any CPU; however some applications that runs ongoing services (IM, Mails, etc) do need to wake up from time to time. – Lie Ryan Dec 16 '10 at 10:53

in your application home/first/main page, press your back key/soft-key/icon.

this is the only common way for closing applications not suspending it.

But that is not closing the application, it's still running in the background. – Jonas Dec 16 '10 at 10:42
Yes, I agree with Jonas .... But I have used some application in which the application closes when we double-press back key/soft-key/icon... – prasonscala Dec 16 '10 at 10:44
