    Is fire transparent, translucent, or opaque? - Quora

    Answer (1 of 2): To begin with, what is fire? Now, we cannot classify fire as matter, because it does not occupy space, right? I mean that you can put your finger inIs there anything which reflects 100% light? - Quora Answer (1 of 8): In case of total internal reflection, all (100%) incident light is reflected back into the same medium. There is no loss of intensity.

    Why Is Aluminum Foil a Better Insulator Than Cotton or

    An area that is already hot will be kept hot by aluminum foil, as it will hold in hot air. Paper and cotton will release heat at a quicker rate than aluminum foil. Aluminum foil can keep things like wires or pipes insulated, as it traps air when it is wrapped around an object.heat transfer - Can aluminium foil be a thermal insulator Sep 16, 2021 The main difference that aluminum foil around an object makes is that it reflects incoming radiation because of its shininess and, because of thermodynamic equilibrium, does not emit significant radiation. Whether the foil touches the object itself or not does not make a large difference since it has very little heat capacity due to its small mass.
