lawyer [7]

Answer:

The value of rate of decrease of volume = - 3600 \frac{k pa}{min}

Step-by-step explanation:

According to Boyle's law P V = C ------- (1)

Pressure ( P ) = 100 k pa = 10 \frac{N}{cm^{2} }

Volume ( V ) = 900 cm^{3}

Put these values in equation ( 1 ) we get,

⇒ C = 10 × 900 = 9000 N-cm = 90 N-m

Differentiate Equation ( 1 ) with respect to time we get,

⇒ V \frac{dP}{dt} + P \frac{dV}{dt} = 0

⇒ V \frac{dP}{dt} = - P \frac{dV}{dt}

⇒ \frac{dV}{dt} = - \frac{V}{P} \frac{dP}{dt} ---------- (2)

This equation gives the rate of decrease of volume.

Given that Rate of increase of pressure = \frac{dP}{dt} = 40 \frac{k pa}{min}

C = 90 N-m

P =  10^{5} pa = 10 \frac{N}{cm^{2} }

V = 900 cm^{3}

Put all the above values in equation 2 we get,

⇒  \frac{dV}{dt} = - \frac{900}{10} × 40

⇒  \frac{dV}{dt} = - 3600 \frac{k pa}{min}

This is the value of rate of decrease of volume.
