An electric resistance heater is installed on side A of the cylinder as shown in the following figure, and it is energized so as to cause the temperature inside A to rise slowly to 445K . If the tank and the piston are perfect heat insulators and are of negligible heat capacity, calculate the amount of heat added to the system by the resistor. The molar heat capacities of the gas are constant and have the values Cv = 12.56J/mol-K and Cp=20.88J/mol-K</span></font></p> <p> <font size="3"> </font> </p><p></p> <p>(대충 한 번역)</p> <p><font size="3">마찰 없이 움직이는 이상적인 실린더가 </font></p> <p><font size="3">처음에<span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">, </span>반으로 구역이 나누어 져 있고<span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">, </span>나누어 진 양 구역은 <span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">1mol</span>의 같은 이상기체가 <span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">278K</span>온도 <span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">100kPa</span>압력으로 존재합니다<span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">.</span></font></p> <p><font size="3">전열기가 그림과 같이 <span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">A</span>쪽에 설치되고<span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">, A</span>의 온도가 <span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">445K</span>까지 오르도록 전류를 보냅니다<span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">.</span></font></p> <p><font size="3">이 때<span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">, </span>탱크와 피스톤이 완전 단열이 되고<span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">, </span>열용량을 무시할만할 때<span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">,</span></font></p> <p><font size="3">전열기로 이 계에 넣어준 열량<span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">(heat)</span>를 계산하시오<span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">.</span></font></p> <p><font size="3"><span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">(C</span><span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;vertical-align:sub;">v</span><span lang="en-us" style="font-family:'함초롬바탕';"> </span><span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">= 12.56J/mol-K, C</span><span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;vertical-align:sub;">p</span><span lang="en-us" style="font-family:'함초롬바탕';"> </span><span lang="en-us" style="font-family:'함초롬바탕';letter-spacing:0pt;">= 20.88j/mol-K)</span></font></p> <p>  </p> <div style="text-align:left;"><img src="http://thimg.todayhumor.co.kr/upfile/201604/146176601256f3a33b9c2c4e9a85d6bdf1ad88de62__mn143359__w779__h277__f13082__Ym201604.png" width="779" height="277" alt="문제.png" style="border:none;" filesize="13082"></div> <div style="text-align:left;"> <div style="text-align:left;"><img src="http://thimg.todayhumor.co.kr/upfile/201604/14617661154194a584085c42b99e537facf253d0c8__mn143359__w720__h960__f71880__Ym201604.jpg" width="720" height="960" alt="계산1.jpg" style="border:none;" filesize="71880"></div> <div style="text-align:left;"><img src="http://thimg.todayhumor.co.kr/upfile/201604/1461766115355e506965ea44edb33724a72061e4a8__mn143359__w540__h960__f59671__Ym201604.jpg" width="540" height="960" alt="계산2.jpg" style="border:none;" filesize="59671"></div></div> <div style="text-align:left;">사진 처럼 계산해서 프로그램 돌려보니 답이 허수가 나와요..</div> <div style="text-align:left;">어디서 잘못 됬는지 모르겠어요 ㅠㅠ</div> <p></p></div>
