Surplus energy is an excess amount and deficit is not enough energy
My opinion on this question, is that gases may come off the bottle, maybe even liquids, if the bottle is frozen enough, solids may drop off it as well.
The average person should watch 30 to 60 minutes a day. An hour is enough for four fifteen minute episodes, and enough for two thirty minute episodes. Isn't that enough? Actually scientists say that its fine if you want to watch 2 hours a day as long as that is the maximum and it isn't every day but technically if you can avoid watching TV all together you should not watch any.
When an empty plastic bottle is left open to the atmosphere the air pressure outside and inside the bottle are in equilibrium (does not always mean they are equal, but in this case they are equal). This means that whatever force exerted by the atmosphere on the outside of the bottle is balanced by a force from the inside of the bottle. When one sucks the air out of the bottle one removes the source of pressure and forces within the bottle. The pressure differential between air outside and inside bottle is enough to cause the bottle to collapse.Note that this will not happen so easily with glass bottles because even when one tries to suck all the air out of them, they also experience a tendency to collapse, but their structure is strong enough to withstand the pressure differences.
Condensation - The surface of the bottle and the air just above it will be cool enough to allow condensation of the water vapor in the air onto the bottle's surface.

The energy saved by recycling one aluminum can is the equivalent to running a TV for four hours.
Recycling just one aluminum can saves enough electricity to run a TV for about four hours.
Cans, steel and aluminum, are 100% recyclable.Making one new can out of aluminum ore takes TWENTY TIMES the energy that it does to make one new can using recycled cans.Every time you recycle ONE aluminum can, you save enough energy to run a TV for three hours!
PaperNo, recycling paper uses less energy (between 40% and 64% less) than if the paper was made from unrecycled wood pulp.Some calculations suggest that recycling one ton of newspaper saves enough electricity to heat and air-condition the average American house for 6 months.GlassNo, recycling glass uses about 40% less energy than making virgin glass from sand, lime and soda, as the furnaces don't need so much energy. Recycling two glass bottles saves enough energy to boil 5 cups of coffee.

There's not enough information to properly answer this question, but I would assume, if the air is inside a bottle of some sort, we're thinking of convection.
Yes it can. Every recycled can saves enough energy to run a TV for three hours.
some schools are not eco-schools because they do not have enough economical things in them e.g. recycling systems or energy saving lamp, light sensors etc
It means projecting enough vocal energy to be heard in the cheap seats at the back of the second balcony in the theater, as opposed to using a microphone for film or TV.
it helps the environment!! that's reason enough!
