Volume of gas at 155. kpa changes from 22.0L to 10.0L...?
few practice questions need help with
1. The volume of a gas at 155.0 kPa changes from 22.0 L to 10.0 L. What is the
new pressure if the temperature remains constant?
2. Is it possible for a balloon with an initial pressure of 200.0 kPa to naturally
expand to four times its initial volume when the temperature remains
constant and atmospheric pressure is 101.3 kPa?
3. Exactly 10.0 L of O2 at 25C is heated to 100.0C. What is the new volume if
the pressure is kept constant?
4. A gas at a pressure of 501 kPa and a temperature of 25C occupies a volume
of 5.2 L. When the gas is heated to 100.0C the volume increases to 7.00 L.
What is the new pressure?
5. A sample of O2 with an initial temperature of 50.0C and a volume of 105 L
is cooled to 25C. The new pressure is 105.4 kPa and the new volume is
55.0 L. What was the initial pressure of the sample?
