Answer:

Your computer now has the IP address of that website cached, and no longer has to lookup the IP address of that domain name. The TTL of the first query is bigger than the TTL of the second query as less time was taken to execute the request.

On the first request to the website, the computer needs to contact other machines to find the record of the IP address.

On the second request, the computer already has the IP address and can use that to connect.
