1 Physics 4C Spring 2016 Test 2 Name: May 17, 2017 Please show your work! Answers are not complete without clear reasoning. When asked for an expression, you must give your answer in terms of the variables given in the question and/or fundamental constants. Answer as many questions as you can, in any order. Calculators are allowed. Books and notes are not allowed. Use any blank space to answer questions, but please make sure it is clear which question your answer refers to. The last question, question 4, is worth by far the most points. g = 9.8 ms 2 P 0 = Pa = 1 atm R = J mol 1 K 1 k B = J/K N A = m p = kg σ = W m 2 K 4 1 cal = J 1 ev = J Fahrenheit to Celsius: ([ F] 32) 1.8 =[ C] Celsius to Fahrenheit: ([ C] 1.8) + 32 =[ F] e = 1 1 (V 1 /V 2 ) (γ 1) v+dv v N v dv = v+dv v ( ) 3/2 m 4πN 0 2πk B T v 2 e m 0v 2 /2k B T dv 1

A metallic block is placed into the water, which has a mass of g and is originally at a temperature of 125 C. The entire system stabilizes at a final temperature of 20.0 C. The specific heat of copper is 387 J kg 1 C 1. Determine the specific heat of the unknown sample. [6 pts] 3

First, in step 1, its pressure is tripled under constant volume. Then, in step 2, it expands adiabatically to its original pressure. Finally, in step 3, the gas is compressed isobarically to its original volume. (a) Draw a PV diagram of this cycle, labeling the steps.
