Two solid objects, a and b, are placed in boiling water and allowed to come to temperature there. each is then lifted out and placed in separate beakers containing 1000 g water at 10.0 ∘c. object a increases the water temperature by 3.50 ∘c; b increases the water temperature by 2.60 ∘c.

Object A must have the higher heat capacity

Explanation:

Because it has stored the most heat. When placed in the other beaker, it releases the most heat by changing the water temperature the most.
