If an object has a low specific heat, does it heat up and cool down quickly or slowly?
It will heat/cool more quickly than a high specific heat compound.
Specific heat is
So, a high value means that it takes MORE energy to raise (or lower) its temperature. A low value means that it does not take very much energy to heat or cool it.
Adding heat to a “low specific heat” compound will increase its temperature much more quickly than adding heat to a high specific heat compound.
