There are many questions which cover your doubts already, I'll link some below. I'll answer your specific questions first:

1) When you visit a website for the first time, actually when you do a session_start() on the PHP side, a new session ID is generated (a random string) and sent to the browser as cookie, usually with the name PHPSESSID, so next time you visit the site the same data is loaded back from the session file (which is stored somewhere on the server)

2) If cookie expires before the session the browser won't send the PHPSESSID value, thus a new session ID is generated. It is usually advisable to use an expire time for cookies way longer. When you expire a cookie, you rely on the client's browser to honor your disposition, but to be safe you must expire the session server side.

3) Sessions won't work, every time the client requests a page a new session cookie will be generated
