Why does water have a high specific heat?

I am writting an essay for AP biology when I realize I am not entirely sure why water has a high specific heat. I thought for a moment it may be because of its polarity and hydrogen bonds keeping the molecules from moving too much too easily in a sense. I only have one day to do that's . I searched google and all I got were pages saying that water has high specific heat, but not why.

Thanks :smile:

Because it is one of the lightest non-linear molecules.

1. low molecular mass - so more moles per kg
2. non-linear molecule - all 3 rotational degrees of freedom contribute to the specific heat

PS : see also NH3
