A 5.00-g pellet of aluminum reaches a final temperature of 63 oC when gaining 200 J of heat. What is its initial temperature?
Answer to relevant QuestionsBlood can carry excess heat from the interior to the surface of the body, where the heat is transferred to the outside environment. If 0.250 kg of blood at a temperature of 37.0 oC flows to the surface and loses 1500 J of ...A student tries to cool his dormitory room by opening the refrigerator door. Will that work? Explain. An ideal gas initially at temperature To, pressure po, and volume Vo is compressed to one-half its initial volume. As shown in Fig. 12.20, process 1 is adiabatic, 2 is isothermal, and 3 is isobaric. Rank the work done on the ...The temperature of 2.0 mol of ideal gas is increased from 150 oC to 250 oC by two different processes. In process A, 2500 J of heat is added to the gas; in process B, 3000 J of heat is added. (a) In which case is more work ...One mole of an ideal gas undergoes an isothermal compression at 0 oC, and 7.5 x 103 J of work is done in compressing the gas.
