A 1.00-L insulated bottle is full of tea at 90.5°C. You pour out a mug of tea and immediately screw the stopper back on the bottle. Find the change in temperature of the tea remaining in the bottle that results from the admission of air at room temperature. (Let the room temperature be 20.0°C and assume that you poured out 205 cm3 of tea. Take the molar mass of air as 28.9 g/mol and ραǐr-1.20 x 10-3 g/cm3. Here we...

Q5. An efficiency consultant is studying the power stroke of a four-stroke engine and determines the following: As the piston is forced down, the mixture of combustion products and air undergoes an adiabatic expansion. The engine is running at 3,100 cycles/min. The gauge pressure immediately before the expansion is 25.0 atm. The volumes of the mixture immediately before and after the expansion are 50.0 cm3 and 400 cm3, respectively (figure below). The time interval for the expansion is one-fourth the...
