Will a hot, dark liquid cool down faster than a hot, light-coloured liquid?

Assuming they have the same starting temperature?








Thanks! :)Will a hot, dark liquid cool down faster than a hot, light-coloured liquid?
Yes. Dark bodies experience greater thermal black body radiation than lighter bodies. You can see a more in-depth explanation in the Best Answer to the question below:

It's very important to note, though, that radiation is emitted at a wide range of frequencies, and this answer is based on the assumption that the body behaves in the non-visible spectrum the same way it does in the visible spectrum, which is not necessarily true, but is often true.Will a hot, dark liquid cool down faster than a hot, light-coloured liquid?
and the same specific heat and everything else that's relevant is the same?





Yes; the dark liquid will lose heat faster by radiation. However, I think that's a relatively minor effect in most circumstances.
no
