A student puts a piece of black paper and a piece of white paper in the same sunny spot after 30 minutes she observed that the black paper feels warmer than the white paper which best explains the students is observation?

The black paper feels warmer than the white paper because black is a better absorber of heat than white. Black objects absorb more light and heat energy from the sun, while white objects reflect light and heat energy. This is why the black paper heats up faster and feels warmer than the white paper when exposed to sunlight.
