Explanation / Answer

     Initial temperature, t =20oC      Final temperature, t' =30oC     Here, t' > t which indicates a rise intemperature.     The rise in temperature leads to thermalexpansion by which, the length     of the pendulum also increases.     As, the time-period of the pendulum increaseswith length, the pendulum     takes more time to complete an oscillation whichresults runnning slow     or loosing time.
