The conical flask with black paint will get hotter, reason of which is mentioned below -
•Black color absorbs all the colours of light while white colour reflects all the colours.
•Since all the rays are absorbed, and every colour has different wavelength and hence energy thus heat energy is absorbed accordingly.
•More heat energy causes temperature to rise while reflection of heat does not increase the temperature.
