Since water has a higher specific heat than copper.

Explanation:

Dimensionally speaking, the specific heat of a material () is represented by:

$[c] = \frac{[Energy]}{[Mass]\cdot [Temperature]}$

The specific heats of water and copper are $4186\,\frac{J}{kg\cdot ^{\circ}C}$ and $390\,\frac{J}{kg\cdot ^{\circ}C}$ , respectively. Let suppose that temperature change and masses of water and copper are the same. Then, a kilogram of water takes a longer time than a kilogram of copper since the first has a higher specific heat.
