Charles’s Law Problems

1) A container holds 50.0 mL of nitrogen at 25° C and a pressure of 736 mm Hg.
What will be its volume if the temperature increases by 35° C?


2) A sample of oxygen occupies a volume of 160 dm3 at 91° C. What will be
volume of oxygen when the temperature drops to 0.00° C?


3) A sample of hydrogen has an initial temperature of 50.° C. When the
temperature is lowered to -5.0° C, the volume of hydrogen becomes
212 cm3. What was the initial volume of the hydrogen in mL?


4) 568 cm3 of chlorine at 25° C will occupy what volume at -25° C while the
pressure remains constant?


5) A sample of helium has a volume of 521 dm3 at a pressure of 75 cm Hg and
a temperature of 18° C. When the temperature is increased to 23° C, what is
the volume of the helium?
.


Answers:
55.9 mL N2
120 dm3 O2
