Question

If the on compressed gas in the above system has a volume of 300.0 mL out of pressure of 20.0 kpa what is the volume of the gas when it is compressed to a pressure of 25.0 kpa

Answer 1

Answer: Volume of the gas when it is compressed to a pressure of 25.0 kPa is 240.0 ml

Step-by-step explanation:

To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.

The equation given by this law is:

`P_1V_1=P_2V_2`

where,

`P_1\text{ and }V_1` are initial pressure and volume.

`P_2\text{ and }V_2` are final pressure and volume.

We are given:

`P_1=20.0kPa\\V_1=300.0mL\\P_2=25.0kPa\\V_2=?`

Putting values in above equation, we get:

`20.0* 300.0mL=25.0* V_2\\\V_2=240.0mL`

Thus the volume of the gas when it is compressed to a pressure of 25.0 kPa is 240.0 ml
