(a) In an experiment, a gas contracts from 0.674 L to 0.243 L under a constant external pressure of 2.138 bar. As this occurs, the gas also transfers 51.3 J of heat to its surroundings. If the gas is considered to be an ideal gas, what is AU (the change in internal energy) for the gas sample in joules (J)? (Note: See the second problem of the Basic Skills 1-2 Quiz to convert work to units of Joules.) (b) At the end of the compression in part (a), the gas is at thermal equilibrium. If the sample consists of 0.0506 moles, what is its temperature?

A student runs two experiments with a constant-volume "bomb" calorimeter containing 1300. g of water (see sketch at right). thermometer stirrer First, a 5.000 g tablet of benzoic acid (C,H,CO,H) is put into the "bomb" and burned completely in an excess of water oxygen. (Benzoic acid is known to have a heat of combustion of 26.454 kJ/g.) The temperature of the water is insulation observed to rise from 23.00 °C to 43.76 °C over a time of 6.8 minutes. Next, 4.260 g of acetaldehyde (C,H,O); are put into the "bomb" and similarly completely burned in an excess of oxygen. This time the temperature of the water rises from 23.00 °C to 38.43 °C. chemical reaction "bomb" Use this information, and any other information you need from the ALEKS Data resource, to answer the questions below about this reaction: A "bomb" calorimeter. 2C,H,0(g) + 50,(g) → 4CO,(g) + 4 H,O(g) Be sure any of your answers that are calculated from measured data are rounded to the correct number of significant digits.

Energy cannot be created nor destroyed, but it can be transferred between a system and its surroundings. The change in internal energy, AU, is positive if the system absorbs energy, and it is negative if the system releases energy. (Figure 1) The total change in internal energy is the sum of the heat, q, and work, w: AU =q+w. Figure 1 of 1 Surroundings AU pystem u System >0 Surroundings AU system System u <0 AU = q + w
