Five moles of monatomic ideal gas have initial pressure 2.50 * 103 pa and initial volume 2.10 m3. while undergoing an adiabatic expansion, the gas does 1480 j of work. what is the final pressure of the gas after the expansion?

pressure of the gas after the expansion is 1795.238 Pa

Explanation:

adiabatic expansion W(+) -  ideal gas:

deriving (1):

⇒ PdV + VdP = RndT

⇒ PdV = RndT - VdP

being the T constant ⇒ dT = 0

⇒ PdV = - VdP(3)

(3) in (1):

⇒ W = ∫ (- VdP )

⇒ W = - V ∫dP

⇒ W = - V * ( P2 - P1 )

⇒ P2 = - ( W / V ) + P1

⇒ P2 = - ( 1480 J / 2,1 m³ ) + 2.5 E3 J /m³

⇒ P2 =  - 704.762 J/m³ + 2.5 E3 J/m³

⇒ P2 = 1795.238 Pa

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
