Can gas return back into a sparkling beverage on cooldown?

We all know that if a sparkling beverage (let’s say, CocaCola) spends some time outside of the fridge and gets warm, the gas comes out of the liquid, rises the inner pressure and makes the bottle walls more tight and the cap to curve outwards. Also, drinking this does not seem very tasty. My question is this: if I cool down the bottle again, will the gas be re-absorbed by the liquid and will the drink restore its qualities?

Edit: sorry, could not add tags like gas or liquid since they do not exist yet :D , and I do not have enough reputation.

How do I fix my humidity problem in my home?

I have an older home. Last year I didn’t have this problem but this winter, to save money I keep my temperature a lot lower. I’m seeing a lot of condensation on the windows and now on my livingroom wall, water running down and mold forming. It also smells like mold in my home. Will purchasing a good dehumidifier help? I am also thinking of adjusting the humidifier on my furnace? Another issue may be that my bathroom doesn’t have an exhaust fan but I can’t afford to have one put in. I need the best, cheapest solution.

Will a cloud form in a depressurized room?

If a room is depressurized will a visible cloud or mist form?

I would expect it would, but when I apply a vacuum to a flask I see no cloud form inside the flask. Would a room behave differently than the flask?

I am more interested in the case of sudden evacuation than a gradual depressurization.

How to prevent condensation inside the camera when taking pictures in a cold place?

Suppose you keep your camera at, say, 20 degrees C at a relative humidity of 60%. This means that the air inside the camera will have the same humidity at the same temperature, the relative humidity will increase if the camera cools down. Then you go outside for several hours where it is -20 C, put your camera on a tripod. After some time the camera will cool down and you will get condensation inside the camera.

The only thing I can think of is to go outside with the camera a day or so earlier, remove the lens and let it sit there for a while, making sure no dirt or snow enters the camera. Then you put the lens back on and put the camera in an airtight bag filled with the outside air. You only get the camera out of the bag the next day when taking pictures outside. However, removing the lens while outside seems to me like a dangerous thing to do, you are bound to get dust inside the camera…

Difference between adsorption and condensation

So I just stumbled across the Wikipedia article on adsorption – and I asked myself, if there is a difference between (physical) adsorption and condensation on a surface?
When I look at the water drops on a cold bottle of your favourite beverage, I think this is covered by what I know about adsorption. Or is this kind of condensation just one of many adsorption reactions?

Any help is appreciated :)

What could cause moisture on my bonus room floor?

Last week during a cold snap with high winds. I discovered moisture along the floor on one side of my bonus room, above the attached garage. Their was enough moisture that the baseboard molding buckled and pulled away from the wall. This occurred on the western facing wall. All other walls / floors were fine with no visible moisture.

I opened up the attic hatch to this area and saw plenty of insulation. Bats in the wall and blown in for the floor area.

I can’t figure out what would be causing this, as the house is 2 months old.

Any ideas?

Is it risky to change lenses in the cold?

I am generally a lazy person, so I am extremely averse to changing lenses on my camera in the cold. I am concerned about my fingers getting cold, but here I read that condensation is extremely dangerous for my camera in cold weather conditions. I understand that condensation occurs when I take my camera from cold air into a warm house, and moisture collects on the lenses. This moisture can harm the interior of the camera, as water does harm to electronics. Besides, water drops can freeze if I leave the warm building for the outside again, so a common advice is to pack the camera into an air-proof bag.

Now, if I am shooting outside, is the camera interior air-proof? Is the air inside the lens and near the sensor warm? Is it dangerous to open the compartment and change lenses outside? How am I supposed to change lens when shooting outside in winter?

Air handler condensation draining problem

For the life of me, I cannot figure this out. My air handler and heat pump were installed in 2006 and work great. For the first summer since I’ve owned the home, condensation started to not drain properly and is leaking onto the filter and onto the basement floor. The inside of this handler is spotless, including the drain pan. I took apart the PVC pipe and cleaned it out well, although I don’t think it needed it. I still have major dripping!

It does not look to me like it should be overflowing. It pours out of the hole circled below and then onto the floor and back into the unit and onto the filter. If it is coming out of this hole, why is it not going down the correct outlet to the pipe?!

enter image description here

The only change point I can think of is that I purchased a box of filters on the web that had a pretty high MERV rating of 12. The fan seems to push air through it pretty easily, but I am wondering if this is somehow producing a vacuum that is not letting the water drain correctly. I removed the plugs pointed out below by the arrows to try and relieve this vacuum, but it did not work. Any thought or advice?

enter image description here

Last night, I cracked open a cold one and just watched in the basement. I can here the water build up in the pan as it makes this gurgling sound like some force is preventing it from draining, but it is on the verge of overflowing. Once the blower stops, all the water drains quickly. Some down the pipe, some out of the that hole. If the water is building up, I simply don’t understand why it won’t drain down the pipe.

The water also drained when I removed the filter and left the cover off while the blower was running.

Condensation running down pipe connecting furnace thru ceiling to chimney

I had a new downflow 80% efficient furnace installed in 2006. I don’t use it regularly as I normally heat my home with my woodstove (separate chimney). But I have used this new furnace many times during “in between” weather, and when I have been out of town. It has always worked fine. Then in 2011, I used the furnace regularly for a few months that winter. I noticed that I had water or condensation running down the pipe that goes from my ceiling to the furnace – it would happen after the furnace ran for a bit. It got to the point that I had to put a pan on top of the furnace to catch the dripping “water”. My immediate thought was that my chimney stack must be cracked as I know the hot air from the furnace meeting the cold air in the stack (if it were cracked) would cause condensation. But after taking off the chimney cap and checking – the stack is fine. My chimney cap was blown off during a windstorm, and now is slightly damaged and sits a bit lower than previously. Could this be causing this problem? I was told by one furnace guy that my chimney stack is too large, and that it needs to be lined to make the opening smaller, and to replace the chimney cap. He swears this will take care of the problem. I’m just wondering why it took 5 years before I had a problem. Could it be because I was not running it 24/7 like I started to in 2011? I hate to pay for all this work if that isn’t the solution?

What thickness Styrofoam should be used to insulate a toilet tank?

So, based on my question here, I like the idea of insulating the inside of the toilet using Styrofoam because it seems more interesting/fun than installing a mixing valve. I plan to use silicone caulk to adhere the Styrofoam to the tank and fill the gaps/seams.

How thick should the Styrofoam be to properly insulate the tank and prevent condensation on the exterior?
