|AP Chemistry - Charles Law Worksheet|
|1.||Give the temperature-volume
law both in words and in the form of an equation.
|2.||How is the volume
of a gas affected by a decrease in temperature?
|3.||What would be the
new volume if the temperature on 450 mL of gas is changed from 45oC
|4.||A sample of
gas whose volume at 27oC is 0.127 L, is heated at constant pressure
until its volume becomes 317 mL. What is the final temperature of the gas
in Celsius and kelvin?
|5.||To make 300 mL of
oxygen at 20.0oC change its volume to 250 mL, what must be done
to the sample if its pressure and mass are to be held constant?
|6.||To what temperature
must an ideal gas at 27oC be cooled to reduce its volume by 1/3?
|7.||From the data in
the following questions calculate the missing quantity.
a) V1 = 22.4 L; T1 = 0oC; T2 = 91oC; V2 = ? L
b) V1 = 125 mL; T1 = ? ; T2 = 25oC; V2 = 100 mL
c) V1 = ? L; T1 = 400 K; T2 = 175 K; V2 = 6.20 L
d) V1 = 250 mL; T1 = 298 K;
T2 = ? K; V2 = 273 mL
|8.||A 50 cm3
sample of a gas in a syringe at 15oC is heated to 50oC
and the syringe's piston is allowed to move outward against a constant atmospheric
pressure. Calculate the new volume of the hot gas.
|9.||What is the final
volume if 3.4 L of nitrogen gas at 400 K is cooled to 200 K and kept at the
|10.||Determine the final
volume of 20 L of a gas whose temperature changes from -73oC to
327oC if the pressure remains constant.
|11.||A partially filled plastic balloon contains 3.4 X 103 m3 of helium gas at 5oC. The noon day sun heats this gas to 37oC. What is the volume of the balloon if atmospheric pressure remains constant.|
