Question

For 1, and 2: A block initially at T = 300 K with T-independent Cv = 25J/K receives a heat input of 10-6 J. What is the dimensioness entropy change of the block? delta sigma= 10-6 3 Times 10-4 7.5-3 2.4 Times 1014 7 Times 1016 if the same energy were instead added to a block 1000 times larger. the entropy increase (compared to the one you just calculated) would be multiplied by: 1/1000 1 1000 Consider two isolated systems of oscillators a and b. Each of the systems has 2 oscillators with energy spacing t. The energy of system a is Ea = 3epsilon, while system b has energy Eb = 2t. Sample microstates are shown. Compare the entropies of a and b. sigma a and sigma b. sigma b - sigma a = -0.288 -1.099 0.288 Systems a and b are brought into contact and allowed to reach equilibrium. Calculate the change in the total entropy: delta sigma = (sigma a + sigma b)equilibrium = (sigma a + sigma b)equilibrium. delta sigma = 0 1.43 0.251 1.54 What is the probability Pa(1epsilon) that in equilibrium the two oscillators on the left(i.e., system a) have total energy 1epsilon. The picture below shows an example microstate: pa(t)= 0.036 0.179 0.286 0.340 0.438
