an equation.

To compress nitrogen at 1 atm from 750 mL to 500 mL, what must
the new pressure be if the temperature is kept constant?
|
| 3. |
If oxygen at 128 kPa is allowed to expand at constant temperature
until its pressure is 101.3 kPa, how much larger will the volume become?
|
| 4. |
A sample of nitrogen at 101.3 kPa with a volume of 100 mL is carefully
compressed at constant temperature in successive changes in pressure, equalling
5 kPa at a time, until the final pressure is 133.3 kPa. Calculate
each new volume and prepare a plot of P versus V, showing P on the horizontal
axis.
