Known : Process 1 : Pressure (P) = 20 N/m 2. Let's look at a particular example. invaluable role. - So far you've seen the First Law of Thermodynamics. Small system obey equations which are symmetric under time reversal, which contra-dicts the second law. The first law asserts that energy is a thermodynamic property. � �K��au�X'gJ2�}�m�����-rNŸ�� �ݻ�/��,?�O�!M���Oe����[ ��Q�n(��hKN����eȾ 0000001526 00000 n %�쏢 0000002322 00000 n 0000098465 00000 n �+4��S� �� ����;����U��>qx���ރ�85~\E���A��}�v}� ��`G��,.>=����mݚ�uײ�W��;����~So� u�&�Y�'�"̑ݔ��-m ��S�,�/`ĭ1��B>�5��B[��ͭ� 0000124831 00000 n 0000002489 00000 n ������k׽���XEb��Y���{\b�k���"�O֝�f��W�/��b }�� �_�ݿl��������erq�m\��Gj��jW�/x�W��f=|^$yvi�l����|��j��)8P�6��8�4���U�I/��^�EQiR�Ф#̻ few laws of thermodynamics called zeroth law, first law, second law and third law. �o�v��(u�7�Z�?t�.�h�*Q��B��� Review of Basic Ideas: Conservation of Energy and the First Law of Thermodynamics Conservation of Energy is one of the most useful and widely used concepts in physics. /U (�&�,���ѽE{y+l ) /P -1852 /V 2 /Length 128 >> endobj 1491 0 obj [ 1492 0 R 1493 0 R 1494 0 R 1495 0 R 1496 0 R 1497 0 R 1498 0 R 1499 0 R 1500 0 R 1501 0 R ] endobj 1492 0 obj << /I << /Title (�)>> /F 73 0 R >> endobj 1493 0 obj << /I << /Title (�)>> /F 74 0 R >> endobj 1494 0 obj << /I << /Title (�)>> /F 75 0 R >> endobj 1495 0 obj << /I << /Title (j)>> /F 76 0 R >> endobj 1496 0 obj << /I << /Title (�)>> /F 98 0 R >> endobj 1497 0 obj << /I << /Title (�)>> /F 99 0 R >> endobj 1498 0 obj << /I << /Title (��)>> /F 18 0 R >> endobj 1499 0 obj << /I << /Title (8P�������)>> /F 31 0 R >> endobj 1500 0 obj << /I << /Title (�)>> /F 32 0 R >> endobj 1501 0 obj << /I << /Title (z)>> /F 33 0 R >> endobj 1502 0 obj << /Type /StructTreeRoot /ParentTree 1476 0 R /ParentTreeNextKey 59 /K [ 218 0 R ] >> endobj 1533 0 obj << /S 2146 /L 2268 /C 2284 /Filter /FlateDecode /Length 1534 0 R >> stream EO 1.3 DESCRIBE the Second Law of Thermodynamics and how it relates to heat transfer. 1.

The First Law of Thermodynamics Work and heat are two ways of transfering energy between a system and the environment, causing the system’s energy to change. 0000009248 00000 n 5 0 obj This is a reasonable assumption since the air is flowing quickly through the vortex tube. 0000006597 00000 n Answer According to the first law of thermodynamics, ∆U = q + W (i) Where, ∆U = change in internal energy for a process q = heat W = work Given, q = + 701 J (Since heat is absorbed) W = –394 J (Since work is done by the system) Page 3 of 11 Website: www.vidhyarjan.com Email: [email protected] Mobile: 9999 249717 Head Office: 1/3-H-A-2, Street # 6, East Azad Nagar, … x��XKo�6��W�(Y��Gom��-rh�rHzHwm���'�R�e��H%� �k6W�f8�f8����Q.�i�;v߽���c�m���L�]t���2�D�x�;����'RP����c�� �9�)_� j,������aèSFy�N���� �� ʕ��\7-�^1&�U�2�dܤ�������U��T�U�*��;�'��^y ���h�ûOr���� �|kF���CA�;���r R�h*��8-֐E. 0000001854 00000 n endobj What is the final temperature of the gas? 5000 J of heat are added to two moles of an ideal monatomic gas, initially at a temperature of 500 K, while the gas performs 7500 J of work. ��P�xl�n"@���tށO���ڂ�ʔ L,uY��1;h���Tu叺rR%������y���G��w8^���с�9 qY��L3T�wG����l 0000001797 00000 n very small systems, and to the whole universe. Energy cannot be created or destroyed; it can only change forms (the first law). Let's see how you use it. Solved Problems on Thermodynamics:-Problem 1:-A container holds a mixture of three nonreacting gases: n 1 moles of the first gas with molar specific heat at constant volume C 1, and so on.Find the molar specific heat at constant volume of the mixture, in terms of the molar specific heats and quantitites of the three separate gases. This means that heat energy cannot be created or destroyed.
