You found that the final temperature of the iced tea is between 0 ∘c and 75.0 ∘c, as the strategy indicated it should be. evaluate the work you did to find the final temperature by considering how it would change if the initial conditions were varied.
you decide to make several more batches of iced tea. the conditions under which you make these batches are identical except that for each batch one initial condition is varied. determine the impact that each of these changes will have on the final temperature of the iced tea.
decrease the volume of the tea.
decrease the mass of ice.
increase the initial temperature of the tea.
decrease the initial temperature of the ice.
sort these changes to the initial conditions of the system based on whether they would cause the final temperature to be smaller than or greater than the temperature of the system found in part c

Acoal-fired plant generates 600 mw of electric power. the plant uses 4.8 x 10^6 kg of coal each day, and the heat of combustion of coal is 3.3x 10^7 j/kg. the steam that drives the turbines is at a temperature of 300° c, and the exhaust water is at 37° c. (a) what is the overall efficiency of the plant for generating electric power? (b) how much thermal energy is exhausted each day? (c) what is the change in entropy of the universe for this heat engine? (d) using the same heat reservoirs, what is the maximum possible (carnot) efficiency for a heat engine?
