Answer:
Explanation:
First of all, I used the specific heat of water as 4182 J/(kgC) and the specific heat of ethyl alcohol (EtOH) as 2440 J/(kgC); that means that we need the masses in kg, not g.
120.g = .1200 kg of ethyl alcohol. Now for the formula:
where spheat is specific heat.
Filling that horrifying-looking formula in with some values:
and
and
16(4182x + 292.8) = 83640x + 2928 and
66912x + 4684.8 = 83640x + 2928 and
1756.8 = 16728x so
x = .105 kg and the amount of water added is 105 g
Answer:
gas is dioatomic
T_f = 330.0 K
Explanation:
Part 1
below equation is used to determine the type Gas by determining value
where V_i and V_f is initial and final volume respectively
and P_i and P_f are initial and final pressure
\gamma = 1.38
therefore gas is dioatomic
Part 2
final temperature in adiabatic process is given as
substituing value to get final temperature
T_f = 330.0 K
Part 3
determine number of moles by using following formula
