This page is designed to help students practice written problems, and is meant to be printed out.  Hit the print command and show all work in the spaces provided.   Final answers must show units, and must be rounded to the correct number of significant digits.

1.  If some neon gas at 121 kPa were allowed to expand from 3.7 dm³ to 6.0 dm³ without changing the temperature,  what pressure would the neon gas exert under these new conditions?

2.  A quantity of gas under a pressure of 1.78 atm has a volume of 550 cm³.   The pressure is increased to 2.50 atm, while the pressure remains constant.   What is the new volume?

3.  Under a pressure of 172 kPa, a gas has a volume of 564 cm³.   The pressure is decreased, without changing the temperature, until the volume of the gas is equal to 8.00 x 10² cm³.  What is the new pressure?

Answers:   1) 75 kPa                                   2) 390 cm³                          3) 121 kPa
