substitute into the equation:
(25 psi)(28 L) (175 psi)(V,)
(313 K)
(593 K)
cross-multiply and simplify:
(25 paiX28 L) (593 K) = (175 psi) (V, X(313 K)
(25 phi)(28 L(593K) (175pei)(V;)TSK)
(175 pi) (313 K)

solve:
V, = 7.6L
Solve the following problems.
1. A canister containing air has a volume of 85 cm' and a pressure of 1.45 atm when the temperature is 310 K.
What is the pressure when the volume is increased to 180 cm' and the temperature is reduced to 280 K?
2. Air is transferred from a 75 L tank where the pressure is 125 psi and the temperature is 288 K to a tire with a
volume of 6.1L and a pressure of 25 psi. What is the new temperature?
3. A helium balloon at 28°C has a volume of 1.8 L and a pressure of 102 kPa. What is the volume of the
balloon when is rises into the atmosphere where the pressure is 85 kPa and the temperature is 4°C?
4. The pressure of a piston with a volume of 650 cm' and 85°C is 830 torr. It is heated to 350°C and
compressed to a volume of 65 cm'. What is the new pressure?
5. A gas tank has a volume of 28.1 m' and a pressure of 18.4 atm. The temperature of the gas is 32°C. What is
the Celsius temperature when the gas is put in an 11.2 m' tank with a pressure of 22.7 atm?
A metal can is able to withstand 3800 kPa before is bursts. The gas in the can has a volume of 235 mL and
the pressure is 110 kPa at 25°C. If the can is crushed to a volume of 8.5 mL and the temperature does not
change will it burst? What is the pressure of the gas in the can?
