a container filled with air at a pressure of 150 kpa a temperature of 27 o c. if the air is heated to 350 o c through an adiabatic process, determine the final pressure, work, and heat transferred.

Respuesta :

A container filled with air at a pressure of 150 kpa a temperature of 27 °c

the final pressure, work, and heat transferred is p=1444.46 Kpa, w=232.23 KJ/KG & Q=0.

Cp = 1.007 KJ/KG

Cv= 0.719 KJ/KG

given T1= 27°c=300k

T2 =350°c=573k

P1=150 kpa

p2= ?

Therefore P1V1=P2V2

P2=1444.46kpa(final pressure)

adiabatic means heat transfer will be zero. Q=0

q=w+Δv

w=-Δv

w=-232.237 KJ/KG

The relationship between temperature and pressure for a given volume of gas is straightforward. Pressure increases in systems when temperature increases and vice versa. The Gay-law Lussac's specifies the link between a gas's pressure and temperature. A rise in air pressure implies a rise in temperature.
