Question

3. 900 J of heat are added to a system and 200 J of work are done on the system. What is ?E? 4. Calculate w for a system that absorbs 260 kJ of heat and for which ?E is 157 kJ. Is the work done on or by the system? 260 = w + 157 w = 103 kJ Work done by the system 5. The internal energy of a system increased by 982 J when it absorbed 492 J of heat. Was work done by or on the system? How much work was done?

260 = w + 157
w = 103 kJ Work done by the system

Step 1

900 J of heat are added to a system and 200 J of work are done on the system. We can use the first law of thermodynamics to find the change in internal energy (∆E): ∆E = Q - W where Q is the heat added to the system and W is the work done on the system. Plugging Show more…
