A bubble of helium gas has a volume 500 mL near the bottom of a tank where the pressure is 1.84 atm and a temperature of 12 degrees Celsius. Determine the bubble's volume once it has risen to the top where the pressure is 1.01 atm and 16 degrees Celsius.
A cylinder of volume 43.8 L helium is filled to a gauge pressure of 1.72 x 10^7 Pa in a cylinder. a) With that amount of helium, how many balloons can be inflated to a volume of 4.0 L and pressure of 1.01 x 10^5 Pa, assuming that the balloons and the cylinder are at the same temperature? b) If the temperature of the balloons is 77 degrees Fahrenheit, then how many moles of helium are in one balloon? c)...
attached is the incorrect answer. Please answer with the correct solution and in Celsius An air bubble of radius 5.5 cm is released from the mouth of a diver. At the diver's depth the pressure is 1.20 atm . (We'll learn in chapter 13 why the diver's depth affects the pressure.) As it rises to the surface, the air inside the bubble does 8.938 J of work. The bubble rises so quickly to the surface that this process can be treated...
A diver observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.45 atm) to the surface (where the pressure is 1.00 atm). The temperature at the bottom is 3.9°C, and the temperature at the surface is 21.3°C. (a) What is the ratio of the volume of the bubble as it reaches the surface to its volume at the bottom?
A diver observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 2.50 atm ) to the surface (where the pressure is 1.00 atm). The temperature at the bottom is 4.0 ∘C and the temperature at the surface is 23.0 ∘C. What is the ratio of the volume of the bubble as it reaches the surface to its volume at the bottom?

2) A 50.0 mL bubble is released from a diver's air tank at a pressure of 3.00 atm and a temperature of 9°C. What is the volume, in milliliters, of the bubble when it reaches the ocean surface, where the pressure is 1.00 atm and the temperature is 25°C? (Assume the amount of gas in the bubble does not change.)
1. A rigid-sided flask contains an ideal gas at temperature 460o C and pressure 4.32 atm. If the flask is now heated to 801 oC, find the new pressure inside the flask, in atm. 2. In a certain heat engine: a fuel-air mixture is injected into a cylinder of volume 6.06 cc at pressure 7.08 atm and temperature 383o C. Now a piston comes down, compressing the gas to a volume 3.03 cc and pressure 64.2 atm. Find the Celsius...
