Don't put them in the microwave either! :-)Р”Р„nd if do perform an experiment - if you use two thermometers or thermocouples, be sure they are calibrated. To remove multiple external variables from your experiment - you might want to place both of the glasses of liquid into a black box (keeping them out of sunlight/away from external heat / light sources). Two of the main attributes you would want to look at in an experiment that would demonstrate this would be 1. There are lists that give the values of emissivity of various materials - in books on spacecraft design, thermal properties handbooks, and similar texts. The 'color' (more precisely, the emissivity) of the surface of the ship will determine whether that portion of the spaceship will be cold, cool, warm, or hot. Р”В®missivity of materials is of significant concern in some industries - for instance - if you are building a spaceship - and you want to keep parts of the spaceship cool or other parts warmer. Given two identical glass containers - one being of one color A and another being of another color B and that they would be filled with, say, some identical heated liquid, and then allowed to cool -Р”Р„nd given that the emissivity of container colored A and the emissivity of container colored B is substantially different, then the rates of cooling would be different. Emissivity would probably be the key differentiator in your question. A number of variables can enter into the picture, so if you conducted an experiment, you'd need to proceed carefully, to avoid skewed results. Mac: Color can affect heat absorption because of emissivity. Absorbed energy is of course not destroyed but usually converted to heat so the answer to your question is yes, makes a difference. another idea might be to set a thermometer under pieces of cloth that are set in the sun or under a lamp to measure different temperatures.Р”Р„nonymous: White reflects more energy than black does. Set the ice in the sun and observe how the darker colors melt down into the ice faster (presuming it will, I've not tried this). rough-surfaced black for example).Р”В¬hris Willard: I would follow Ben Franklin's observations, put different colors on a block of ice (he used snow).

Try some materials with different reflective surfaces too (foil shiny black vs.

They're cheap, don't break, are flat so you can put them under a piece of paper (if that's what material you're using) to check your temperatures. Try using thermometer strips sold at pet stores (to stick on the insides of reptile cages to monitor temperature). JP: As you probably already know, dark colors (black) will heat up more than light colors (white). Heat Absorption and Emissivity - Information from others Has anyone tried to set that one up?Р”В¬olor and Heat Absorption - from 'Ask a scientist'Р”В¬olor and Heat Absorption - from MadScientst Network #3 - Is it better to use a light source or the sun? Ben Franklin's research with cloth and snow sounds interesting. #2 - When using a thermometer, is it better to use cloth or construction paper? #1 - I am doing a science fair experiment on color vs. This is a compilation of information from students who are conducting scientific color experiments about color and heat absorption.
