- One way to cool a gas is to let it expand. When a certain gas under a pressure of 5.00 106 Ha at 25.0C is allowed to expand to 3.00 times its original volume, its final pressure is 1.07 106 Pa. (a) What is the initial temperature of the gas in Kelvin? (b) What is the final temperature of the system? (See Section 10.4.)arrow_forwardA weather balloon filled with helium gas has a volume of 300 m³ and pressure 1.4 x 105Pa at the Earth's surface (where the temperature is 293 K). The balloon is then released and moves to a high altitude, where the pressure in the balloon is 8.95 x 10*Pa and the temperature is 250 K (-23°C). What is the new volume of the balloon?

The balloon rises to a location where the temperature is -10.0°C and the pressure is 20.0 kPa. If the balloon is free to expand so that the pressure of the gas inside is equal to the ambient pressure, what is the new volume of the balloon? Assume that in both cases the hydrogen gas is in thermal equilibrium with the outside air. O 14.0 m³ 4.16 m³ 16.0 m³ 41.7 m³ 2.38 m³arrow_forward
- 17. A clown at a birthday party has brought along a helium cylinder, with which he intends to fill balloons. When full, each balloon contains 0.034 m³ of helium at an absolute pressure of 1.2 X 10$ Pa. The cylinder contains helium at an absolute pressure of 1.6 × 107 Pa and has a volume of 0.0031 m². The temperature of the helium in the tank and in the balloons is the same and remains constant. What is the maximum number of balloons that can be filled?arrow_forwardA car tire has an inner radius of 45.46 cm has a low pressure of 195 kPa. The tire is recommended to be inflated to 248 kPa. At the low pressure the tire outer radius is 56.65 cm and fully inflated is 67.81 cm. The outside temperature is 17 0C. What is the mass of the air to inflate the tire? How many air molecules are added to properly inflate the tire?arrow_forwardA hot air balloon holds 7.40 x 107 liters of gas. In order for the hot air balloon to rise into the sky, it must be heated to 120°C. Once the balloon is up in the air, the air needs to be cooled in order for the balloon to land.
