Hi please help: a bubble with original volume 2.5 cm^3 rises from the bottom of a lake to the surface where it grows to a volume of 5.9cm^3 at a pressure of 1.0 atm. Gas molecules were absorbed by the water as the bubble rose so that only 82% of the original gas is in the 5.9 cm^3 bubble at the surface. The temperature at the bottom is 8.2 degrees Celsius and the temperature at the surface is 23.4 degrees Celsius. Find the pressure at the bottom of the lake (in atm). Use 3 significant figures
7. Containers A and B in the figure to the right hold the same gas. The volume of B is four times the volume of A. The two containers are connected by a thin tube (negligible volume) and a valve that is closed. The gas in A is at 300 K and pressure of 1.0 × 10³ Pa. The gas in B is at 400 K and pressure of 5.0 × 105 Pa. Heaters will maintain the temperatures of A and B even after the valve is opened A 300 K Valve B 400 K a) After the valve is opened, gas will flow one way or the other until A and B have equal pressure. What is the final pressure? b) Is this a reversible or an irreversible process? Explain..
Amanda discovers that the gauge pressure in her car tires is 2.50 ×105 Pa at a temperature of 35.0oC. The average volume of a single tire at that temperature is 10.0 L. 1.) Find how many moles of gas (air) are in one of Steve’s tires. 2.) Later Amanda travels to a place where the temperature is –40.0oF. She notices that the tires are looking low and estimates that each tire has lost approximately 1.0 L of its volume. What is the gauge pressure in the tire now?

1. People buying food in sealed bags at high elevation often notice that the bags are puffed up because the air inside has expanded. A bag of pretzels was packed at a pressure of 1.00 atm and a temperature of 22.0 C. When opened at a summer picnic in Santa Fe, New Mexico, at a temperature of 32.0 C, the volume of air in the bag is 1.13 times its original volume. What is the pressure of the air P Santa Fe? = 0.079 Santa Fe X atm
A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a. If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.
