Air is compressed from 2.8 l, 17 degree c and 95 kpa to 0.41 l inside a piston-cylinder device. the compression is reversible and adiabatic. r_air = 0.287 kj/kg. k. using variable specific heat analysis, determine: a. the temperature after compression, in k. b. the pressure after compression, in kpa. c. the work done on the system, in kj.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
