40. Gloves are often worn to protect the hands from being burned when they come in contact with very hot or very cold objects. Gloves are often made of cotton or wool, but many of the newer heat-resistant gloves are made of silicon rubber. The spe- cific heats of these materials are listed below: Material Specific heat (Jlg°C) wool felt 1.38 cotton 1.33 раper 1.33 rubber 3.65 silicon rubber 1.46 a glove with a mass of 99.3 grams composed of cottorn increaes in temperature by 15 3°F. how much energy was 1.bsorbed by the glove? )A glove with a mass of 86.2 grams increases in temperature 25.9 F when it absorbs 1.71 kJ of energy. Calculare the opecific heat of the glove and predict its composition. (c) If a glove with a mass of 50.0 grams needs to absorb 1.65 kJ of energy, how much will the temperature of the glove increase for each of the materials listed above? Hhich is the best material for a heat-resistant glove? If you were designiga he -resistant glove, what kind of specilic heat would you look for
