Chemistry
Conduct an experiment to determine the specific heat, c, for unknown metal #1 (under solids tab). Use the formula: c = (q)/(m)(T) where q = heat the metal lost; m = mass of the metal; and T = the change in temperature of the metal (metal and water end at same temperature value). (Note: An assumption in this type of calorimetry problem is that in an ideal system the heat the metal lost = heat the water gained.) Use a set up like you did in the experiment in #2 above to determine how much heat, q, the WATER GAINED and use this value for “q” of the metal, that is, the heat the METAL LOST. Be sure to briefly describe your experiment, record all measurements made, and to show all calculations for determining the specific heat of the metal.

The sand and water end up at the same temperature. The sand consists of material that all has the same specific heat. The relations between temperature change and heat lost by the water and gained by the sand can be written separately as: (1) where and are the specific heats of water and sand, respectively. By assumption, the heat gained

'Motile' (or moving) cilia are found in the lungs, respiratory tract and middle ear. ... These cilia have a rhythmic waving or beating motion. They work, for instance, to keep the airways clear of mucus and dirt, allowing us to breathe easily and without irritation.
