Question

A 1.00-L insulated bottle is full of tea at 91.0°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 225
cm^{3} of tea. Take the molar mass of air as 28.9 g/mol and
*ρ*_{air} = 1.20 10^{-3}
g/cm^{3}. Here we define a "monatomic ideal gas" to have
molar specific heats C_{v}= 3/2 R and
C_{p}= 5/2 R, and a "diatomic ideal gas" to have
C_{v}= 5/2R and C_{p}= 7/2R.

=________ degrees C
