Question

carla did an experiment by placing a piece of smooth, clear glass and a piece of smooth, black stone under a lamp for twenty minutes. which prediction will most likely be supported by carlas experimental results? the glass will feel warmer than the stone after twenty minutes. the stone will feel warmer than the glass after twenty minutes. the glass will reflect all of the light after twenty minutes. the stone will reflect all of the light after twenty minutes.

Explanation:

Black surfaces are better absorbers of light and heat compared to clear glass. When exposed to a lamp, the black - stone will absorb more light energy and convert it into heat, making it warmer than the clear glass which allows light to pass through and absorbs less heat. Also, clear glass does not reflect all light (it is transparent) and a black stone is a good absorber and not a perfect reflector.

Answer:

The stone will feel warmer than the glass after twenty minutes.
