1.                 Determine how many liters of hydrogen adjusted to STP there are in a 50.0 liter steel cylinder if the pressure inside is 100.0 atm and the temperature is 27.0^oC.

 

 

 

2.                 A sample of a gas that exhibits ideal behavior occupies a volume of 350.0 mL at 25.0^oC and 95.0 kPa. Determine its volume at 600.0^oC and 20.0 kPa.

 

 

 

3.                 A sample of gas occupies 14.3 liters at 19.0^oC and 110.0 kPa. What volume will this amount of gas occupy at 190.0^oC and 11.00 kPa?

 

 

 

4.                 On a hot day the pressure in an automobile tire increases. Assuming that the air in a tire at 15.0^oC increases in pressure from 1.93 atm to 2.07 atm,  (a) what is the temperature of the air in the tire under isometric (constant volume) conditions?  (b) What will be the pressure if the temperature rises to 42.0^oC?

 

 

 

5.                 A closed gas system initially has pressure and temperature of 1350 torr and 526.0 ^oC with the volume unknown. If the same closed system has values of 1240 torr, 7.80 L and 780 K, what was the initial volume in mL?

 

 

 

6.                 A closed gas system initially has pressure and temperature of 1.46 atm and 886.0 ^oC with the volume unknown. If the same closed system has values of 0.947 atm, 4040 mL and 578 K, what was the initial volume in L?

 

 

 

7.                 A closed gas system initially has pressure and volume of 1.41 atm and 8.34 L with the temperature unknown. If the same closed system has values of 1.84 atm, 2050 mL and 305 K, what was the initial temperature in K?

 

 

 

8.                 A closed gas system initially has volume and temperature of 8.54 L and 776.0 ^oC with the pressure unknown. If the same closed system has values of 1.88 atm, 6080 mL and 959.0 ^oC, what was the initial pressure in torr?
