# Why are lakes and oceans are able to stabilize air and land temperatures?

Aug 11, 2017

${H}_{2} O$ has a heat capacity over four times larger than that of ${N}_{2}$. Heat capacity is how much energy a substance can absorb before its temperature changes.
However, as you look at the planet as a whole, water-worlds are the most stable, temperature-wise, all due to the unique physical properties of ${H}_{2} O$. And, in many localized areas, this stability can be demonstrated all the way down to the swimming-pool size. That's where I like to sit!
