If you had stood outside looking up with your mouth open in the UK's worst snowstorm in the past 10 years, how long would it taken for the snow to fill your mouth with 200ml of water?

Would it have been more energy efficient to keep yourself warm all that time or to transport that 200ml of water to a tap in the area that the snowstorm happened?

I've been dropping squash balls at different temperatures from a constant height of 1m, and measuring the height they bounce up to. I understand that as you heat the squash balls, air molecules inside the ball (which has negligible increases in mass and volume) bounce again each other and the inside of the ball more often and harder, leading to more air pressure in the ball, and thus a higher bounce. Is there any equation that links pressure or temperature with a drop height and bounce height? I've been using Boyle's law, Charles law and the pressure law to find pressure, and there are existing formulae for volumes, of course, but how can I link pressure with bounce? I assume it will involve the coefficient of restitution somewhere, but I'm unsure. Thanks a lot! :)

I know the air inside the lungs makes people float and just like that,the air inside a ship decreases the density of the total volume and hence makes the ship float.But what happens if you vacuum the air inside the ship and then seal it somehow,just like exhaling air from your lungs,does the ship sink cause the density of the total volume will just be the density of them metals inside the ship despite the airless big space in it?

If you played the same note, in 500 versions of exactly the same speakers (so all the same frequencies) at the same distance from the receptor (ear or decibel meter), would it be the same volume? 

If it would increase, how much by and why? 

Would it be 500 times? Or would some be cancelled out?

Thanks!
