Question

240 cm^3 of air at a pressure of 100k pa in bicycle pump is compass to a volume of 150 cm^3.What is the pressure of the compare in the pump​

Answer 1

Answer:

160k Pa

Explanation:

Initial volume, V1=240cm^3

Final volume, V2=150cm^3

Initial pressure, P1=100k Pa

Final pressure(By Boyle's law) =P1×V1/ V2

=160k Pa

Answer 2

The final pressure is 160 k pa.

Explanation:

The pressure and volume relation at constant temperature is given as

$P_1V_1=P_2V_2$           (Boyle's Law )

Here, $P_1$ is the initial pressure and P_2 is the final pressure and V_1 and V_2 are the initial and final volumes respectively.

Given $V_1=240cm^3,P_1=10 \ kPa, V_2=150cm^3$

Substitute these value in above equation, we get

$P_2=\frac{240cm^3\times100kPa}{150cm^3}$

$P_2=160kPa$

Thus, the final pressure is 160 k pa.
