isolate for 100meters in all directions. does not burn but will support combustion, can react explosively with fuels, and containers may explode when heated. first aide move to fresh air administer 02, and keep the victim warm and quiet. 1075- butane, propane, liquefied petroleum, and propylene; extremely flammable and will cause explosive gases when mixed with air. DO NOT try to extinguish a fire unless the leak can be stopped.
The products of a combustion reaction are carbon dioxide and water. I also found out that it takes skill to light a match and that it’s difficult to keep gas where you want it to be without a sealed container. There are many sources of error. The first source of error was that if you blow on the candle too hard, the wax vapor blows away and the flame doesn’t jump. The next source of error is that if you don’t put in the limewater and stopper quickly enough, the carbon dioxide escapes and the water won’t turn chalky.
Do this before it cools or water will travel backwards into your tube and contaminate your solid product. I 1 Collecting a liquid product: If you loosely wrap a damp paper towel around the upper-outer section of the boiling tube away from the flame, you might be able to condense a gaseous produCt into its liquid ·state. In addition to this you should cut a large piece of qualitative filter paper in half and then fold it and theri curl it inside the boiling tube near the rubber stopper. If a liquid forms, the finer paper will help absorb it and prevent it from falling back onto the solid being heated. Make sure the rubber stopper is securely in place since gas can easily leak out.
To keep the colors from fading, washing the fabric and drying it is good, but the key ingredient is soda ash. You sprinkle soda ash into a tub of water and let your fabric soak for a minute or two. The soda ash will lock in your dye and make your colors more vibrant and they will be less likely to fade. You can find soda ash in most craft stores. The amount of soda ash to use varies so it is a good idea to read the directions before adding it.
(With resistance) Air: with resistance, syringe A can still be pushed a little towards syringe B. this is because particles in air are spread out; there are room in between to particles. That is why when syringe A is pressed down, the particles compressed together tightly causing the syringe to move a little before the particles were impacted too tightly for the syringe to move Water: water particles are different from gas particles. Water has very little compressibility. Particles in water are much more compacted together, therefore giving no space for them to compress more. This is the reason why with resistance, syringe A will not move as the particles in water are as tightly compressed together as they can get.
The capsule will soften but not completely dissolve in the water, however will dissolve in the Hydrochloric Acid. The Tablet will slowly dissolve in water, however more rapidly in Hydrochloric Acid – however loosely comparable to the dissolving tablet. Equipment * Water * 2M Hydrochloric Acid * Test Tubes or Beakers * Stopwatch * 2 x Aspirin Enteric Coated Tablets * 2 x Aspirin Capsule * 2 x Regular Aspirin Tablets * 2 x Dissolving Aspirin Tablets * Safety Glasse * (Recommended) Gloves for handling Hydrochloric Acid Safety Precautions * 2M Hydrochloric Acid will burn both skin and clothing * Always wear eye protection while handling Hydrochloric Acid * Avoid contact with
According to Science Buddies in the article Measuring Surface Tension of Water with a Penny, water “molecules at the surface experience a net force pulling them inward” (2007). For instance, if you filled a cup with water to the very top, adding a few more drops of water will make the glass overfill without spilling any actual water because the water molecules are being pulled inward. While water has a unique, high surface tension, other liquids, like olive oil, do not. The cause of low surface tension in olive oil is due to “Van Der Waal” forces. While hydrogen bonds have a uniquely high surface tension, van der Waals forces have a relatively weak attraction, which causes low surface tension.
It doesn't, it only leads to losing water weight. No fat loss. Two ways to deal with dehydration Move the dehydrated person to a cool area so he/she can cool down, put a cool cloth on his/her forehead. - Sip water slowly. If you drink too much water, your cells can expand and eventually burst, which can be dangerous.
Some might think that by squeezing the bottle, Mr. Squiddy would go up with the water however, he would go down due to the pipette being used. The pipette had a little air bubble at the top of it, when the bottle was squeezed the water filled into the pipette creating an increase in pressure and a subsequently decrease in volume causing Mr. Squiddy to sink. When released, the high pressure subsided and he floated back up. In the crushing cans demo the cans were heated up with a little water inside and set to boil until steam appeared. Once the can was hot enough it was quickly placed in a bowl of ice cold water and the can crushed itself.
Leaving it ¾ full would leave room for some motor oil and the rag which will act as a wick. Next you will pour some motor oil into the glass bottle, at least half a shot glass of it. Finally you will take the rag which usually needs to be soaked in some kind of flammable liquid, and you either pack one end of the rag into the neck of the bottle, leaving the other end of the rag hanging out as a fuse, or you can simply cover the top of the bottle with a stopper or tape and tie the rag to the top of the bottle which is probably the safer approach. Once you have done this your Molotov is ready to go and you can go ahead and light the rag which will act like the fuse. The blast radius of a Molotov is at least 5-7 feet all around and flames can reach as high as 4-5 feet off of the ground.
