1. A sample of C4H10 at 110 °C experiences a qnange in volume from 2000 mL to 7 L. If its
new pressure is 600 kPa at 270 K, what was its original pressure in kilopascals?
2.
The temperature of 800 mL of BrCl is changed from 110 °C to 1000 K. During this, the
pressure also changes from 10 kPa to 0.5 atm What is the new volume of the gas in
milliliters?
3.
A sample of H2Se experiences a change in pressure from 6000 torr to 0.2 atm. During this
change, the temperature is also changed from 170 °C to 300 K. If its new volume is 800
mL, what was its original volume in milliliters?
