Consider the following model of the is curve without an international sector: consumption: latex: \frac{c_t}{\bar{y}_t} = \bar{a}_c - \bar{b}_c (r_t - \bar{r}) c t y ¯ t = a ¯ c − b ¯ c ( r t − r ¯ ); investment: latex: \frac{i_t}{\bar{y}_t} = \bar{a}_i - \bar{b}_i (r_t - \bar{r})i t y ¯ t = a ¯ i − b ¯ i ( r t − r ¯ ); and government expenditure: latex: g_t = \bar{a}_g \bar{y}_tg t = a ¯ g y ¯ t. note that latex: \bar{b}_cb ¯ c can be a positive or negative real number. with this formulation, the is curve is: group of answer choices

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
