3) The enthalpy of vaporization $\Delta H_v$ is given by the Clausius-Clapeyron equation $\Delta H_v = R \left(\frac{T_2 - T_1}{T_1T_2}\right) \ln\left(\frac{P_2}{P_1}\right) = RT_1T_2(T_2 - T_1)^{-1} \ln\left(\frac{P_2}{P_1}\right)$ For water, the vapor pressures at the following temperatures have been measured. $T_1 = 283.15 \text{ K}$ $P_1 = 9.2 \text{ torr}$ $T_2 = 313.15 \text{ K}$ $P_2 = 55.3 \text{ torr}$ $R = 8.3145 \text{ J/mol K}$ $\Delta T = \pm 0.1 \text{ K}$ Calculate $\Delta H_v$ and the uncertainty in $\Delta H_v$. $\Delta P = \pm 0.1 \text{ torr}$

Which statement is generally false? Control counting loops with integer values. Indent the statements in the body of each control structure for clarity. Put a blank line before and after each major control structure to make it stand out in the program. The more deeply nested a program is, the easier it is to understand.

If $f(t)$ is continuous for $t \ge 0$, the Laplace Transform of $f$ is the function $F$ defined by $F(s) = \int_0^\infty f(t)e^{-st} dt$ and the domain of $F$ is the set consisting of all numbers $s$ for which the integral converges. Find the Laplace transforms of the following functions. (Enter domains as inequalities.) (a) $f(t) = 38$ $F(s) = \text{________}$ with domain ${s \text{________}}$ (b) $f(t) = 22e^t$ $F(s) = \text{________}$ with domain ${s \text{________}}$ (c) $f(t) = 21t$ $F(s) = \text{________}$ with domain ${s \text{________}}$

For each of the following statements, state whether it is TRUE or FALSE, fully justifying your answer. If you simply answer TRUE or FALSE, you will be awarded no marks. a) Prospect Theory explains why the same person might buy insurance and gamble, by proposing that people have a value function that is concave in gains and convex in losses. b) In Prospect Theory, reference dependence means that assets' payoffs are compared to the expected payoff and coded as gains/losses. c) Historically, stock market participation has been inexplicably high.
