Question

what is the minimum pressure required to compress 460 decimeter cube of air at 2 bar to 230 DM cube at 30 degree Celsius

Answer 1

According to the boyle's law
P=k1/V
PV=k
P1V1=P2V2
460×2=P2×230
920=P2×230
P2=4 bar

Answer 2

Answer: Minimum pressure that might be required will be 4 bar.

Explanation: To calculate the pressure required to compress a gas at a given temperature, we use Boyle's Law,

Equation for Boyle's Law is:

$P_1V_1=P_2V_2$

Initial conditions are:

$P_1=2bar$

$V_1=460dm^3$

Final conditions are:

$P_2=?bar$

$V_2=230dm^3$

Putting all the values, in above equation, we get:

$2\times 460=P_2\times 230$

$P_2=4bar$
