Explanation / Answer

When the pendulum of a grandfather clock is heated, the clockruns more slowly. [ correct ]
Since when pendulum heated then its length is increases.So, it runsslowly
In a bimetallic strip of brass and copper which curls whenheated, the brass is on the inside of the curve. [ incorrect] Since coeffcient linear expansion of copper ( 16.8 * 10^ -6 / oC ) is less tahn brass ( 18.9 * 10 ^ -6 /oC )

An aluminum plate has a hole cut in its center. When the plate isheated, the hole gets smaller. [ incorrect ]
Cold objects do not radiate heat energy. [ incorrect]
When heat is added to a system, the temperature mustrise. [ correct ]
When the Celsius temperature doubles, the Fahrenheittemperature doubles [ incorrect ]
