Answer:
Explanation:
due to Isobaric system, the pressure is kept constant -
Work = Pressue( V_i - V_f)
WHERE
V_i IS INITIAL VOLUME
V_f is final volume
Work = 2.0*10^5 Pa (0.824 - 1.00x10^{-3})
Work = 1.64x10^5 J
B)
increase or decrease in internal energy can be calculated by using following relation:
by keeping temperature and pressure constant, Q can be calculated from the phase change.
Q = (mass)(Heat of Vaporiztion)
Q = (1 kg)(2.20 *10^6) = 2.20 * 10^6 J
If a hummingbirds diet is composed mainly of honeysuckle
nectar, it would require 10g/0.020g * 15 seconds for sugar = 2.08 hours = 124.8 minutes
8g/0.010g * 15 for protein = 3.3 hours = 216 minutes
If a hummingbirds diet is composed mainly of nasturtium nectar,
it would require 10g/0.010g * 20 seconds for sugar = 5.5 hours = 330 minutes
<span>8g/0.010g * 20 for protein = 4.4 hours = 264 minutes</span>
U=10m/s
acceleration due to gravity=9.8/3=3.27m/s^2
t=12s
s=ut+1/2at^2
s=10(12)+1/2(3.27)(12)^2
s=355.2m
