A weather balloon is filled with 80 L of hydrogen gas. The pressure at ground level is 89 kPa, and the temperature is 21 degrees Celsius. As the balloon rises to a certain altitude, the pressure drops to 15 kPa, and the temperature decreases by 90 degrees Celsius. What is the volume of the balloon at this altitude? *Note: Temperatures must be converted to standard (Kelvin).

Which of the following would have less momentum than a 52 kg cheetah running at 10 m/s?

Acetylene gas c2h2 undergoes combustion to produce carbon dioxide and water vapor how many grams of water are produced by the same amount of c2h2?

How do cfcs cause ozone depletion? how do cfcs cause ozone depletion? ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule.
