24 Suppose that the labour force is currently 5.5 million and the unemployment rate is 13%. On August 1, government announces that it will create 50,000 new jobs to be filled over the next three months. Only people who were unemployed on August 1 will be hired. As a result, 120,000 people immediately apply for the jobs; half of these people had previously not been actively seeking work. a. Has the labour force changed as a result of this announcement? Yes, the labour force has changed as a result of this announcement. No, the labour force has not changed as a result of this announcement b. The unemployment rate after the announcement but before the jobs are filled will be ____%. Enter your responses rounded to one decimal place. c. Once all the jobs are filled, the unemployment rate will be ____%

Entropy. Suppose the heat capacity of some system has the form $C_v = aT + bT^3$ for temperatures from zero up to some temperature of interest. Calculate its entropy at temperature T. Under what conditions is your result valid? Suppose there is a phase change at some temperature less than T, and, like the melting of water, that phase change requires some input of heat. Discuss how that would change your approach to finding the entropy. You might use, $C_v = T \left(\frac{\partial S}{\partial T}\right)_{V, N}$ $S(U, V, N) = N k_B \left\{ \ln \left[ \frac{V}{N} \left( \frac{4 \pi m U}{3 h^2 N} \right)^{3/2} \right] + \frac{5}{2} \right\}$
