My computer has an old dual-core CPU with 1 GiB
of RAM
On normal work, such as using firefox, the CPU usage is more than 50%, and if I open more than couple browser tabs, it happens lag because of the high CPU usage
Is it a normal CPU usage or there's something hung in the system? What can I do about it?

The main reason for installing a lightweight version of Ubuntu such as Xubuntu or Lubuntu is to get better performance. If you want to get better performance, you should try using a lightweight *buntu version, even if your hardware will support Ubuntu and Unity.
