<span>Answer:
We have pressure from the weight of the piston + atmospheric pressure acting on the gas
pressure from the piston...
P = F / area = mass x acceleration due to gravity / area
P = (24 kg x 9.80 m/s²) / (90 cm² x (1m/100cm)²) = 26133 N/m² = 2.61x10^4 Pa = 26.1 kPa
total pressure acting on the gas = 26+85 kPa = 111 kPa
then.. via clausius clapeyron equation..
ln(P1 / P2) = (dHvap / R) x (1 / T2 - 1 / T1)
and if I pick say.. the normal boiling point of water for P2, T2.. then...
P1 = 111 kPa
P2 = 101.325 kPa
dHvap = 40680 J/mole
R = 8.314 J/moleK
T2 = 373.15 K
T1 = ??
---> T1 = 102.46°</span>
Answer:
140 beats per minute
Explanation:
There are 60 seconds in a minute and we know that Sherry felt 14 beats in 6 seconds if you multiply 6 by 10 you get 60 seconds which can be 1 minute. Then you multiply 14 by 10 since you 14 by 10 since you multiplied 6 by 10 and you get 140 beats per minute.
